WebIn SAS®, the LIFETEST procedure is commonly used to generate survival estimates based on the Kaplan Meier estimator [2] for lifetime data with only right censoring. However, as of version SAS/STAT® 14.3, it is not capable of adjusting left truncation. The PHREG procedure on the other hand can be used to analyze left truncated data by setting the WebGatekeeping Procedures • Gatekeeping procedure is a multiple testing procedure to address: Multiplicity issues: multiple endpoints, dose-control comparisons, objectives, different time points – With hierarchical structure of hypotheses: hypotheses often can be grouped into families to reflect hierarchical nature
WebThe same procedure will be applied to H 2, H 5, and H 6. If one wishes to use a more powerful method such as Hochberg, it can be done for the second family among H 3 and H 4 (or H 5 and H 6). Instead of equally splitting α/2 between H 3 and H 4, one can compare the larger p-value of H 3 and H 4 with α/2 and reject both of the hypotheses if p ...
