a) for a1_N_1_S, going to the bounds implied by the SE will not change the sign of the average slope only up to length interval 4 ? after that the SE generally will;
b) for a1_N_1_C, the SE will only change the sign of the average slope in two cases out of the 12: length intervals 3 and 7;
c) in both cases, SE increases considerably with length but ?much more so? (?) for a1_N_1_C than for a1_N_1_S.
If it?s legit to draw conclusions from comparative behavior of SE?s in contrasting sets of results like these, then interesting scientific interpretations can be made of the above SE behaviors. But I?ve learned not to jump the gun by making such interpretations based on illegitimate interpretations of statistical behaviors. So, guidance please, when you have a chance.
Also, regarding point (c) above, if it?s legitimate in general to look at SE behavior in such results sets, is there a legitimate way to show that the SE?s for a1_N_1_C really do increase significantly MORE with increasing length interval than SE?s for a1_N_1_S? Or not? Again, guidance please.
And thanks again as always for your continued consideration of these matters.
