Stratified Sampling Python. Cases when every unit from a given population has the same probability of being selected. Read more in the user guide. scikit learn Python Split data into n stratified parts Stack Overflow from stackoverflow.com

Use a regression algorithm and compare accuracy fo each predicted value. Im looking for a fast pandas/sklearn/numpy way to generate stratified samples of size n from a dataset. In this step, the population is divided into strata based on similar.

### When Comparing Both Samples, The Stratified One Is Much More Representative Of The Overall Population.

The first step in performing the stratified sampling would be importing the pandas library. Use a regression algorithm and compare accuracy fo each predicted value. Stratified sampling helps you to save cost and time because you'd be working with a small and precise sample.
