Hi Raul, Thanx for responding. There is nothing special about Y - it is a list of 50 numbers which is a machine learning fit of the supplied function and could simply be considered a noisy version of it. I .e Y is something like
R =. (50?1e3)%1e3 Y =. 50 1$^((-i.50)%10) + R-mean R where 'mean' is: mean =. +/ % # (R -mean R) is intended to be a zero mean sample of Gaussian noise - however I cant seem to find how to draw Gaussian samples in J without implementing the Ziggurat algorithm or such - a tip here would also be appreciated!
