### Purpose

White-Noise-Test

### Description

This function performs a Portmanteau test for white noise
yielding the significance of the signal not being white noise.
Return parameters (also shown in the message window) are

- test value
`Qm` and
- the significance
`signif`, i.e. the probability [0..1] of x
to be a random white noise process "by chance", where small values indicate significant differences from a white noise process.
