Scipy stats normal test
Webscipy.stats. kstest (rvs, ... Performs the (one-sample with two-sample) Kolmogorov-Smirnov test for goodness of fit. The one-sample take comparing the background distribution F(x) of a sample against a given distribution G(x). The two-sample test see the underlying distributions by two independent samples. Both test are valid only for ... Web13 May 2024 · In the histogram of the garage area variable, we can clearly see that the distribution is not uniform (normal).
