But it's the best known of the information criteria and if we dropped it I guess we would have people saying, why don't you print the AIC? Here's another go at this topic. I've put up http://ricardo.ecn.wfu.edu/~cottrell/dougherty/table.html showing a few variants for folks to consider. * Version A is what I posted yesterday. It is closely (too closely?) based on eviews and does not have a space for the HQC; also it prints the Durbin-Watson statistic regardless of whether or not the data are time series (but does not print rho). We probably don't want this. * Version B is what Jack suggested yesterday (although it doesn't fully correspond with his preferences since it omits the HQC). It prints rho and DW only for time series. * Version C is what I'm inclined to favour at present. * Version D is what Jack canvassed in a later patch. I'll make a case for C, though I'm not totally committed to this. First, I don't think it's necessary to print the sample size in this table, since we always show that in the header for model output. Second, it's obviously a matter of opinion whether it's "more logical" to have closely related items (e.g. the F-stat and its p-value) on the same row (as in Jack's B) or next to each other vertically (as in C). I find that my eye tends to group things vertically given this sort of presentation, so I have a slight preference for C in this regard. Thoughts? Allin. _______________________________________________ Gretl-devel mailing list Gretl-devel(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-devel
