Problem Note 37577: BASELINE statement CMF estimates ignore the OFFSET= option
Cumulative Mean Function (CMF) estimates should equal the cumulative hazard estimates from the BASELINE statement CMF= and CUMHAZ= keywords. When the OFFSET= option is specified we no longer have equality between these estimates. The CMF computation ignores the OFFSET value.
To circumvent the problem, use the CUMHAZ estimates.
