test for two samples
...need to compare two samples, to
reject one technique (the worse one), and to keep the one which gave
lower residuals (better one). What to look for? What should I analyse?
Means, variance, std. deviations?
Based on preliminary EDA:
mean_resid1 < mean_resid2 #I would reject resid2 technique
stdev_resid1 > stdev_resid2 #I would reject resid1 technique
var_resid1 > var_resid2 #I would reject resid1 technique
Based on means I would reject resid2 technique, but based on analyses of
stdev. and variance I would reject resid1 technique.
How to deal with that problem? What is proper statist. atr...
