ST_CM_MovingMoments_InitPars

Function-block-specific structure with initialization parameters, which are analyzed when the function block is initialized.

• nChannels defines the number of independent channels. This must be greater than zero.
• nSubChannels defines the number of independent subchannels. This must be greater than or equal to zero.
• nInLength defines the length of the input data array.
• nPopulation defines the size of the internal data buffer for calculating the moving moment.
• bPopulationEstimates is a Boolean value that indicates, whether the corresponding Bessel's correction is applied to the sample variance, skew and excess.
• bKurtosisExcess is a Boolean value that specifies whether the excess is reduced by the value of the kurtosis of a normal distribution.
