Re: count model

there do have "v=1" in eq33 and eq36, or eq33 use other form of QML standard errors (not the Huber/White method)? my summary: for negative binomial model 1 if v=num is given, the variance is fixed, thus not estimated by EViews. Otherwise estimated and reported as "SHAPE" 2 to QML...

Re: ordered model

hmm, just now I've found that the following command will cause error

Code: Select all

eq02.makelimits(v) lv   'cov of limit points

if I remove the comment, it will work

Ordered forecast, latent variable or probability

Hi

In ordered model, when forecasting using models obj, there also find some inconsistent forecast, the fitted probability indicates category 2 (max prob), however the latent variable forecast to be lied in category 3.

which one is to be chosen? latent variable or probability?

Nearest Neighbor Fit

ver 7.1
user guide I P519
Local Weighting (Tricube): If you turn this option off, each local regression will be unweighted with w_i =1 for all i.
My question: W_i=1 for obs in nearest neighbor, and zero outside the neighbor. Subset only, not full set of obs, right?

Re: hist vs distplot

thanks
on histograms, distplot is more full-featured and customizable. I just feel a bit odd that hist sometimes behave like "distplot hist(rightclosed)" and at other time like "distplot hist"

Re: hist vs distplot

Thanks.
I first think that "hist" is equivalent to "distplot hist". now I know it is not, "hist" may adjust something like bin, anchor and how obs on end-point are handled.
