Wilcoxon's sign rank test

Wilcoxon's sign rank test It is suitable for paired comparison in T-test, but it doesn'T need to find that the difference between pairs of data obeys normal distribution, only requires symmetrical distribution. Verify that the difference between pairs of observations comes from a population with a mean of 0 (the population tha ...

Basic usage of Numpy

1. Create an array with Numpy numpy.array(object): to create an array, unlike array.array(typecode [, initializer]), array.array() can only create one-dimensional arrays Numpy.range (start, stop, step, dtype = none): create a one-dimensional array (step is the best integer) starting from start and ending at stop (excluding stop), with step as t ...
