Survival models based upon the logistic and log--logistic distributions.
LOGC and LOGLOGC are interactive FORTRAN programs which fit the logistic and log--logistic regression models to censored survival data. Maximum likelihood estimates of parameters and estimates of their standard errors are given together with the corresponding log-likelihood. Survivorship functions, median remaining lifetimes and estimates of confidence intervals for these functions are given. Residual plotting is incorporated to assess the goodness of fit and can be plotted as can the survivorship function and median remaining lifetime estimates together with their corresponding confidence limits.
