Calcuation of STND residuals

[Bruce Southey <southey@uiuc.edu>]

Hi,
Could someone please tell me how the STND RES are calculated?
I can not get these residuals from the .yht file.
The attached is a simple example with a fixed effects only model.

I ran the analysis with and without the data point - S^2 is the variance
with it and S(i)^2 is the variance without.  Res and Hat are the
residuals and Hat value from the .yht file.

As per pg 376-377 of McCullagh and Nelder
Stand Res was calculated as Res /(sqrt(1-Hat))
Student Res was calculated as Stand Res/S
Del Stud Res was calculated as Student Res * S / S(i)

S^2         S(i)^2    Res     Hat      Stand Res        Student Res   
Del Stud Res
1.55357	0.758523	4	0.1295	4.287218357	3.439617822	7.044858309

The value from the .res file is 3.32.

Also, in at least this version of ASREML, potential outliers are those
with STND RES of >3.3 rather than the 3.5 said on page 115 of the March
21, 2000 manual.

Thanks 
Bruce
