WebApr 24, 2024 · Another possibility is for the coxph function to fail to converge. This occurs when the maximum likelihood estimate of a coefficient is infinity, e.g. if one of the treatment groups has no events. The coxph documentation states that the Wald statistic should be ignored in this case and therefore the rpsftm output should be taken with caution. port st lucie state house of representatives https://aileronstudio.com
