I do not recall that -somersd- (an -eclass-command) produces a matrix
result -r(table)-. What program did you use to produce -r(table)-, and
how did you do this?
Best wishes

Hi all,
I am using Newson's -somersd- command (from ssc); results, including the
piece I want, are saved in a matrix and I can list that matrix:
. mat list r(table)
r(table)[9,1]
yhat1
b .62563699
se .00834334
t 74.986391
pvalue 3.73e-257
ll .60924043
ul .64203354
df 452
crit 1.9652262
eform 0
My problem comes in attempting to use the [1,1] term (.62563699 here);
for example, I can't seem to list it:
. matrix li r(table)[1,1]
[ invalid name
matrix [1,1] not found
r(111)
and I can't do what I want to do - add this value to a scalar:
scalar cstat=cstat+r(table)[1,1]
invalid syntax
r(198)
note that cstat is not the problem as it is defined (as 0) prior to
entering my loop
clearly I am doing something wrong but I have been unable to figure out
what it is or how to fix it
