Problem Note 38391: Wald confidence limits from the HAZARDRATIO statement in the PHREG procedure might be incorrect with PARAM=GLM coding
 |  |  |  |  |
If you use the GLM parameterization, the Wald confidence limits provided by the HAZARDRATIO statement might be incorrect. These incorrect Wald confidence limits include those for the hazard ratios of any CLASS variables and of a continuous variable that has an interaction effect with a CLASS variable. For example all of the following HAZARDRATIO statements produce some incorrect Wald confidence limits:
The point estimates of the hazard ratios from the HAZARDRATIO statement are not affected, nor are the profile likelihood confidence limits. The CONTRAST statement provides a potential work-around if you need to compute custom hazard ratios and confidence limits when using PARAM=GLM coding.
