WebIn explanatory modeling, we use regression to determine which variables have an effect on the response or help explain the response. In this context, we are generally interested in identifying the predictors that tell us the most about response, and in understanding the magnitude and direction of the model coefficients. In statistical modeling, regression analysis is a set of statistical processes for estimating the relationships between a dependent variable (often called the 'outcome' or 'response' variable, or a 'label' in machine learning parlance) and one or more independent variables (often called 'predictors', 'covariates', 'explanatory variables' or 'features').
