I have for a few weeks measured the time it takes for a product to be released through a automated release pipeline. I have several different categorical features such as "Product Category", "Product Owner". Then I also have some numerical categories such as "Hour of day when started the job", "Number of sub products" and more. In total I have around 16 different categories, where each category can take around 10 different values.
I will now try and train a regression model to see if I can predict the lead time(time it takes for the product to go through the pipeline) based on these features.
I would want to see if there are any of these features which are more correlated with the lead time than others. As I have understod it I have to seperate the numerical and categorical features and perform tests seperately on them. For numerical variables I have read about pearsonr and for correlating categorical and numerical variables I have read about ANOVA but I can't seem to find any way of implementing ANOVA in Python. Has anyone any experience with this? And if not, any other tips on how to do this?
