Here is what I typed into SAS, where did I go wrong?
data a;
input age $ Hosp Nhosp;
off=log (Nhosp);
datalines;
18-29 3 10323 0.000291 0.03
30-49 23 13450 0.00171 0.2 5.9
50-64 37 5307 0.006972 0.7 24.0
65-79 77 2014 0.038232 3.8 131.6
80+ 73 653 0.111792 11.2 384.7
;
proc genmod;
class age(ref="18-29");
model Nhosp=age / dist=poisson offset=off;
lsmeans age / diff=control("18-29") exp cl plots=none;
run;
Here is the log:
1 data a;
2 input age $ Hosp Nhosp;
3 off=log (Nhosp);
4 datalines;
NOTE: SAS went to a new line when INPUT statement reached past the end of a line.
NOTE: The data set WORK.A has 5 observations and 4 variables.

NOTE: Fitting saturated model. Scale will not be estimated.
NOTE: Algorithm converged.
NOTE: The scale parameter was held fixed.
NOTE: The structure of the LSMeans table has changed from an earlier release of SAS.
NOTE: The structure of the Diffs table has changed from an earlier release of SAS.
