Настройка параметров метода «Нелинейная регрессия»

Ниже приведен пример использования операции SetMs для изменения параметров уравнения. В запросе передаются: экземпляр открытого контейнера моделирования, параметры выполнения операции, настройки уравнения для метода «Нелинейная регрессия» и шаблон получения измененных данных. В результате выполнения операция возвращает модель, содержащую измененное уравнение.

Для выполнения примера уравнение должно содержать входную и выходную переменные.

Функция SetMsNonLinearRegr изменяет метод расчёта уравнения. Входные параметры:

ms. Экземпляр открытого контейнера моделирования;
modelKey. Ключ модели, содержащей уравнение;
eqKey. Ключ уравнения;
eq. Экземпляр открытого уравнения. Для выполнения примера уравнение должно содержать входную и выходную переменные.

В результате выполнения функция возвращает модель, содержащую уравнение.
