Fit method in pandas
WebThe fit method generally accepts 2 inputs:. The samples matrix (or design matrix) X.The size of X is typically (n_samples, n_features), which means that samples are represented as rows and features are represented as columns.. The target values y which are real numbers for regression tasks, or integers for classification (or any other discrete set of values). WebGetting started. This very simple case-study is designed to get you up-and-running quickly with statsmodels. Starting from raw data, we will show the steps needed to estimate a statistical model and to draw a diagnostic plot. We will only use functions provided by statsmodels or its pandas and patsy dependencies.
