Cumulative sums of squares of a series.
Increasing samples calculation of the sum of the squared values in x.
Syntax: @cumsumsq(x[, s])
x: series
s: (optional) sample string or object
Return: series
Compute the cumulative sum of the squared values in x from the start of the workfile or sample s, up to the current observation:
This function is panel aware.
Examples
series x = @cumsumsq(@nrnd) / (@trend + 1)
generates a random process x that converges in probability to 1.
