Changes in version 1.2.0 (2025-12-04) New features - The ahreg() function has been introduced to enable regression analysis for the average hazard. - print.ahreg() method has been added to provide formatted output from ahreg(). Changes in version 1.1.2 Changes - The ah1() and ah2() functions check the input data to make sure time does not involve 0 or negative numbers. - An example for stratified analysis is added for ah2(). - print.ah2() is updated to produce a nicer output. Changes in version 1.1.1 Changes - The ah1() function is now provide the variance for RMST and cumulative incidence probability as well as averaage hazard. Changes in version 1.1.0 New features - Added the eta argument to ah2() to allow calculation of the average hazard within a specified time window [eta, tau]. - Added the strata argument to ah2() to enable stratified analysis. Changes - The ah1() function is now exported and available for estimating the average hazard in a single sample (previously a hidden function). Changes in version 1.0.0 (2023-01-17) - Initial release.
