Testowanie wielokrotne przy weryfikacji wieloczynnikowych modeli proporcjonalnego hazardu Coxa
Multiple testing in the verification process of multifactorial cox proportional hazards models

Summary/Abstract: One of the stages of verifying Cox proportional hazards model is testing statisti-cal significance of its parameters, each at the level 𝛼, disregarding the fact of multiple test-ing. Disregarding it results in taking wrong decisions concerning statistical significance of factors, which are, in fact, insignificant. Applying the procedures of multiple testing allows for confirmation whether the remaining factors have been regarded as significant only be-cause of multiple testing during the verification of their statistical significance.
