0.99 (June 9, 2007) This is the last release before version 1.0! * Added full profiling to the "ml" and "mppl" methods in coxreg. * mlreg is now deprecated. Use coxreg with method = ml or = mppl 0.98 0.97 0.96-7 (Dec 29, 2006) * Corrected a bug in the documentation of 'weibreg'. 0.96-6 (Dec 28, 2006) * Corrected a bug in weibreg concerning 'center = FALSE'. 0.96-5 (Oct 24, 2006) * added a 'terms' object to the output of coxreg and mlreg. 0.96-1 (May 15, 2006) * plot.Surv improved. Suggestions by Dimitri Szerman. (Thanks!) 0.96-0 (April 14, 2006) * Weibull regression updated; It is now possible to fit a Weibull model to left-truncated and right-censored data without covariates. A small error in the documentation of 'weibreg' corrected. 0.94-3 (Aug 22, 2005) * 'check.surv': If the 'id' was a factor with unused labels, the result was unpredictable. Corrected. 0.94-2 (Jun 27, 2005) * Errors in the documentation of 'weibreg' corrected. 0.93-0 (Sep 20, 2004) * NAMESPACE introduced for R-2.0.0. 0.92-4 (May 5, 2004) * coxreg: 'Error' changed to 'warning' for a singular hessian, in which case the new return value is NULL. 0.92-3 (March 19, 2004) * table.events: New parameter: 'strict = TRUE'. * make.communal: In case of 'communal=FALSE', spells are no longer truncated. Instead a value of NA is given if birthdate is out of range. Previous behavior was unpredictable when birthdate was out of range. 0.92 (November 12, 2003) * mlreg: Geometric distribution (i.e., constant baseline discrete hazard) added. Not for frailty models, yet (on the TODO list). * mlreg: New argument, 'n.points', added to 'control'. Controls the number of points used in the Gauss-Hermite quadrature. * mlreg: Stricter control of numerical problems, especially in the frailty fit. * clean: Replaced by check.spells and join.spells. * Return values changed to conform with R-1.8.0 (and later).
