Data Drift Report
Drift Report service creates a statistical report based on a comparison of training and production data distributions. It compares these two sets of data by a set of statistical tests and finds deviations.
Drift report uses multiple different tests with p=.95 for different features:
Numerical features:
Levene's test with a trimmed mean
Welch's t-test
Mood's test
Kolmogorov–Smirnov test
Categorical features:
Chi-Square test
Unseen categories
Supported Models
Right now Drift Report feature works only for Models with numerical scalar fields.
