Step4: Encode the data set (i am using .cat.codes) Step5: Change back the value of encoded None into np.NaN. Step5: Use KNN (from fancyimpute) to impute the missing values. Step6: Re-map the encoded dataset to its initial names. Share. Improve this answer.
Parametric tests usually have stricter requirements than nonparametric tests, and are able to make stronger inferences from the data. They can only be conducted with data that adheres to the common assumptions of statistical tests. The most common types of parametric test include regression tests, comparison … See more Statistical tests work by calculating a test statistic – a number that describes how much the relationship between variables in your test differs from … See more You can perform statistical tests on data that have been collected in a statistically valid manner – either through an experiment, or through observations made using probability … See more This flowchart helps you choose among parametric tests.
