Re: st: error message single sample unit

[Steven Samuels <sjhsamuels@earthlink.net>]

Sahid-

I don't understand your question.  I see two options, neither of  
which is difficult.

1. In -svyset-, set the -singleunit- option to something other than  
the default "missing".  I  suggest singleunit(centered).  This  
setting will apply to analyses of other variables with single units.

2. Create a new stratum variable for the analysis of sd107f  by  
merging single unit strata to adjacent ones.  This assumes that  
strata with adjacent numbers are "near" each other in some physical  
sense.

For example:

gen st_sd107f = v012  //your stratum
recode st_sd107f 19=20  27=28  29=30   etc.

Then prior to analyses of this sd107f,  -svset- your data again  with  
the new stratum variable.
