nonlinear correlations

Postby ponec » Thu Nov 24, 2011 2:39 pm

as there is no significiant autocorrelation structures in time series, so Ive tried PCA on 10 dimensional recurent data (9 lagged variables) to spot nonlinear correlations and then plot output and make automactic classification, but guess what, it doesnt work :|

ps. Ive tried many approaches and the fact that some observations from C class are different is pretty visiable - density of statistics of observations in class C is slightly deformed
