How to Carry Out Bivariate Statistical Test in PythonTest the predictor feature statistically at bivariate, before including it in the model — Do you know? Using boxplots, scatterplots, and other visualization tool is awesome but never enough in confirming that a relationship exists between two variables (The target feature (Y)and each of the predictor features(X))? I know you may ask, why? Well, because a statistician may argue that the visual pattern you…Statistics31 min readStatistics31 min read
Published inAnalytics Vidhya·Feb 10, 2021Visualization, not enough to suggest a relationship; Confirm it with a Statistical testVisualization is never enough to conclude that a relationship exist between the two Variables. It is best to confirm it Statistically. — When preparing data for modeling or analysis, one of the known practices is, to conduct a data visualization of the target feature (Y) with each of the predictor features (X) so we can roughly see if any relationship/association exists between them. The truth is, using visualization only is never enough…Data Science11 min readData Science11 min read
