-# 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/).

-## 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
