+# Statapp
+
+![Release info](https://img.shields.io/github/v/release/shizand/statapp)
+![Python version](https://img.shields.io/badge/python-3.8-blue.svg)
+[![Codacy Badge](https://app.codacy.com/project/badge/Grade/c4e370d74a8a4575b79afa8b9b74d130)](https://app.codacy.com/gh/shizand/statapp/dashboard?utm_source=gh&utm_medium=referral&utm_content=&utm_campaign=Badge_grade)
+![License info](https://img.shields.io/github/license/shizand/statapp)
+
+Автоматизированное программное средство по статистическому анализу и регрессионному моделированию. Является идейным продолжателем программы STAT.exe (Produced by Reutov V.N., Donetsk University, 1990).
+
+Разработано двумя студентами ФГБОУ ВО «ДонНТУ» для своего университета.
+
+## Поддерживаемые ОС и архитектуры
+
+В теории, должно работать на любой архитектуре и ОС, где запускается Python 3.8 и есть Qt 5.
+
+Работоспособность проверена на x64:
+
+* на Windows 7, 10;
+* на ALT Linux 10.2.
+
+## Установка
+
+Программа распространяется с помощью [PyInstaller](https://pyinstaller.org/en/stable/).
+
+Существует две версиии: **statapp** и **statapp-onefile**.
+
+Различия в том, что onefile версия поставляется одним единственным бинарным файлом. На Windows системах с включенным антивирусом это может вызывать [некоторые проблемы](https://qna.habr.com/q/988553).
+
+### Готовые двоичные файлы
+
+[Скачайте архив](https://github.com/shizand/statapp/releases) под вашу платформу и распакуйте в любом месте.
+
+### Сборка из исходников
+
+В этом проекте используется [poetry](https://python-poetry.org/).
+
+```bash
+poetry install
+pyinstaller statapp.spec # или pyinstaller statapp.spec -- --one-file
+```
+
+Документация собирается с помощью [grip](https://github.com/joeyespo/grip)

+
+## Краткие теоретические сведения
+
+В рамках ***дисперсионного анализа*** для каждой величины вычисляются следующие характеристики.
+***Математическое ожидание*** характеризует среднее значение величины:
+
+<image src="files/Формула 1.PNG">
+
+*где n – количество значений величины, i – номер значения.*
+
+***Дисперсия*** характеризует разброс величины относительно среднего значения:
+
+<image src="files/Формула 2.PNG">
+
+***Среднеквадратичное отклонение*** характеризует разброс величины относительно среднего значения:
+
+<image src="files/Формула 3.PNG">
+
+В результате ***корреляционного анализа*** вычисляется ***корреляционная матрица***. ***Коэффициент корреляции*** (rij) характеризует взаимосвязь между величинами.  Взаимосвязь считается сильной, если выполняется условие:
+
+<image src="files/Формула 4.PNG">
+
+Знак ***коэффициента корреляции*** показывает характер влияния величин. Если знак положительный (прямая связь), то увеличение значения одной величины приводит к увеличению значения другой. Иначе увеличение значения одной величины приводит к уменьшению значения другой (обратная связь).
+
+При осуществлении каскадного регрессионного анализа вычисляются параметры и оценки модели. В основе анализа лежит понятие коэффициента значимости (tj), который характеризует степень влияния фактора на модель. Фактор считается значимым, если выполняется условие:
+
+<image src="files/Формула 5.PNG">
+
+На каждом шаге вычисляются оценки полученной зависимости.
+
+***Остаточная дисперсия масштабированная*** показывает, какая часть статистического материала не была охвачена полученной зависимостью.
+
+<image src="files/Формула 6.PNG">
+
+***Отношение Фишера*** (F1) показывает во сколько раз полученная зависимость лучше полинома y=yср, где yср – математическое ожидание y.
+
+<image src="files/Формула 7.PNG">
+
+***Коэффициент множественной детерминации*** (R) характеризует степень близости полученной зависимости к реальному поведению объекта.
+
+<image src="files/Формула 8.PNG">
+
+Механизм процедуры ***каскадного регрессионного анализа***.
+
+На 1-м шаге анализа строится модель, которая включает все ***факторы***. Далее производится исключение ***фактора*** tj с наименьшим по модулю значением ***коэффициента значимости*** и строится новая модель. Если оценки модели ухудшились, то ***каскадная процедура исключения факторов*** останавливается и лучшей считается модель, полученная на предыдущем шаге. Иначе исключение ***факторов*** продолжается до тех пор, пока не ухудшатся оценки модели либо пока  для всех ***факторов*** будет выполняться условие.
+
+## Начало работы
+
+### Генерация показателей
+
+<hr>
+
+### Генерация отклика
+
+Перед тем как начать анализ, необходимо сгенерировать ***отклики***, которые будут использоваться как зависимые переменные в моделях:
+
+1. Перейдите в меню `Генерация показателей`.
+2. Выберите `Генерация отклика`.
+
+После этого откроется окно `Генерация отклика`:
+
+<image src="files/Генерация показателей - Генерация отклика.PNG">
+
+*Пример пункта меню* `Генерация отклика`
+
+3. Укажите необходимые параметры для генерации данных и нажмите кнопку `Сгенерировать`.
+
+<image src="files/Окно - Генерация отклика.PNG" width=400>
+
+*Пример окна* `Генерация отклика`
+
+После этого окно должно закрыться и на `Белом листе` в `Главном окне` появится колонка со случайно сгенерированными данными отклика по заданным показателям.
+
+<hr>
+
+### Генерация фактора
+
+После генерации ***откликов*** следует сгенерировать ***факторы***, которые будут служить независимыми переменными. Для генерации ***факторов*** необходимо выполнить следующие шаги:
+
+1. Перейдите в меню `Генерация показателей`.
+2. Выберите `Генерация фактора`.
+
+После этого откроется окно `Генерация фактора`:
+
+<image src="files/Генерация показателей - Генерация фактора.PNG">
+
+*Пример пункта меню* `Генерация фактора`
+
+3. Выберите нужный тип связи к ***отклику*** (прямая или обратная).
+4. Укажите оставшиеся параметры для генерации данных и нажмите кнопку `Сгенерировать`.
+
+<image src="files/Окно - Генерация фактора.PNG" width=400>
+
+*Пример окна* `Генерация отклика`
+
+Можно добавлять несколько факторов.
+
+<hr>
+
+### Удаление факторов
+
+Так как программа `Statapp` генерирует показатели ***Факторов*** случайным образом в границах заданого ***Среднеквадратического отклонения*** то при генерации нескольких ***Факторов*** может возникнуть необходимость удаления некоторых из них. Для этого необходимо выполнить следующие шаги:
+
+1. Выберите необходимый ***Фактор*** для удаления и кликните по `Заголовку` с обозначением `Xn` правой кнопкой мыши.
+2. Нажмите на появившуюся кнопку `Удалить` для удаления выбранного ***Фактора***.
+
+*Внимание после удаления ***Фактора*** действие уже нельзя будет отменить*
+
+<image src="files/Окно - Удаление.PNG">
+
+*Пример появившейся кнопки* `Удалить`
+
+Удаленный ***Фактор*** пропадет из таблицы и более не будет учитываться в `Анализе` и `Моделировании`.
+
+<hr>
+
+### Анализ данных
+
+После генерации ***отклика*** и ***факторов*** можно приступать к анализу данных.
+
+<hr>
+
+### Дисперсионный анализ
+
+1. Перейдите в меню `Анализ данных`.
+2. Выберите `Дисперсионный анализ`.
+
+<image src="files/Анализ данных - Дисперсионный анализ.PNG">
+
+*Пример пункта меню* `Дисперсионный анализ`
+
+После этого откроется окно `Дисперсионный анализ`:
+
+<image src="files/Окно - Дисперсионный анализ.PNG">
+
+*Пример окна* `Дисперсионный анализ`
+
+<hr>
+
+### Корреляционный анализ
+
+1. Перейдите в меню `Анализ данных`.
+2. Выберите `Корреляционный анализ`.
+
+<image src="files/Анализ данных - Корреляционный анализ.PNG">
+
+*Пример пункта меню* `Корреляционный анализ`
+
+После этого откроется окно `Корреляционный анализ`:
+
+<image src="files/Окно - Корреляционный анализ.PNG">
+
+*Пример окна* `Корреляционный анализ`
+
+<hr>
+
+### Моделирование
+
+После генерации отклика и факторов можно перейти к построению регрессионных моделей.
+
+Здесь вы можете увидеть параметры модели, её характеристики, прогноз и отклонения, а также график прогноза и отклонения.
+
+1. Перейдите на вкладку `Моделирование`.
+2. Выберите тип модели для построения: `Линейный полином`, `Квадратичный полином` или `Преобразования`.
+
+<image src="files/Моделирование - Линейный полином.PNG">
+
+*Пример список пунктов меню* `Моделирование`
+
+На странице `Модель` любого окна из `Моделирование` можно увидеть данные ***Коэффициент регрессии*** и ***Коэффициент значимости*** в виде таблицы для отклика и каждого из факторов. В нижней части окна располагаются вычисленные значения для параметров: ***Остаточная дисперсия***, ***Остаточная дисперсия (масштабированная)***, ***F1 - отношение Фишера***, ***Коэффициент множественной детерминации***,
+
+<image src="files/Окно - Полином (Линейный полином).PNG">
+
+*Пример страницы* `Модель` *окна* `Линейный полином`
+
+На странице `Прогноз` любого окна из `Моделирование` можно увидеть значения ***Прогноза*** и ***Отклонения*** для каждого ранее сгенерированного значения ***Отклика***.
+
+<image src="files/Окно - Полином - Прогноз.PNG">
+
+*Пример страницы* `Прогноз` *окна* `Линейный полином`
+
+На странице `График` любого окна из `Моделирование` можно увидеть график ***Прогноза*** (график) и ***Отклонения*** (точки).
+
+<image src="files/Окно - Полином - График.PNG">
+
+*Пример страницы* `График` *окна* `Линейный полином`
+
+При необходимости, в окне `Моделирование` - `Преобразования` для каждого фактора вы можете выбрать одно из доступных преобразований.
+
+<image src="files/Окно - Полином (Преобразования).PNG">
+
+*Пример окна* `Преобразования`
+
+Для выбора преобразования для определенного фактора необходимо выполнить следующие шаги:
+
+1. Перейдите на страницу `Модель` в окне `Преобразования`.
+2. Дважды нажмите на нужную ячейку в колонке ***Преобразования***.
+3. Выберите необходимое преобразование из выпадающего списка.
+
+<image src="files/Преобразования - Выбор преобразования.PNG">
+
+*Пример списка выбора* ***Преобразования*** *фактора в окне* `Преобразования`
+
+*Комментарий: если значения не персчитались попробуйте снять выделение с ячейки, путем нажатия на другую ячейку*
+
+<hr>
+
+### Сохранение и открытие файла
+
+Сгенерированные значения ***отклика*** и ***фактора*** из таблицы в `Главном окне` можно сохранить или зугрузить из файла ***.txt*** и ***.csv***.
+
+### Сохранение файла
+
+1. Перейдите в меню `Файл`.
+2. Выберите `Сохранить`.
+
+<image src="files/Файл - Сохранить.PNG">
+
+*Пример пункта меню* `Сохранить файл`
+
+3. Выберите путь сохранения и тип файла и нажмите кнопку `Сохранить`.
+
+Теперь файл будет сохранен по указаному вами пути, его можно переместить куда необходимо и при необходимости загрузить обратно в приложение.
+
+### Открытие файла
+
+1. Перейдите в меню `Файл`.
+2. Выберите `Открыть`.
+
+<image src="files/Файл - Открыть.PNG">
+
+*Пример пункта меню* `Открыть файл`
+
+3. Выберите путь до открываемого файла и нажмите кнопку `Открыть`.
+
+Приложение загрузит нужный вам файл, и при необходимости спросит нужно ли сохранять ваши текущие данные.
