The ISmLogisticRegression interface is used for data mining using the Logistic Regression method.
ISmLogisticRegression
This method is used to predict probability of a certain event based on a number of features. For example, if you need to predict whether a certain patient has a disease based on patients' age and gender. This analysis can be used only for binary data.
An explained series must be an array of binary values that indicate the presence or the absence of a characteristic. If observation is set to Double.Nan, it means that observation is skipped and it is required to find whether the characteristic is present. Explained series must represent categorical data.
