.This function uses a numerically unstable algorithm. If you need numerical stability in calculations, use the corrStable function. It works slower but provides a lower computational error. Syntax s... Constant floating-point number from 0 to 1. We recommend using a level value in the range of [0.01, 0.99] . Default value: 0.5. At level=0.5 the function calculates median . expr — Expression over...
