A SAS macro for estimating direct adjusted survival functions for time-to-event data with or without left truncation

Detailed formulae to estimate direct adjusted survival functions and their variances are published [6]. Constructing confidence bands and computing simultaneous p values is described by Wang and Zhang [8]. For left-truncated data,the risk-set needs to be appropriately adjusted at estimating time individually.Improvements in computational performance%adjsurvlt() has several computational enhancements. First, instead of repeating large blocks [...]
