Logistic Regression (ML_CN_1)

This function performs analysis on a dataset and returns the predicted binary outcome based on the input independent variables.

This function analyzes a dataset in which there are one or more independent variables that determine an outcome. The outcome is measured with a dichotomous variable (in which there are only two possible outcomes).

It is used to predict a binary outcome (1 / 0, Yes / No, True / False) given a set of independent variables. The model is based on the relationship between the independent variables and the probability of the binary outcome.

Logistic regression models the probability that an event belongs to a certain category, then makes predictions based on the maximum likelihood of the observed data.
