use the LIFETEST to test if different levels of covariates have the same effect on the survival curve. We are doing hypothesis testing for each predictor: H0:SSEX=0=SSEX=1 vs. H1:Not H0 H0:SMI=1=SMI=2=S(MI=2) vs. H1:Not H0 H0:SCAGE=0=SCAGE=1=SCAGE=2=S(CAGE=3) vs. H1:Not H0 First, we will test the equality over SEX, and compare the KM curve using LIFETEST and PHREG.

important concept when doing statistical tests. For example, suppose you have a 2x2-table and you want to apply the chi-square test for independence between rows and columns. The chi-square test is based on the assumption that you already know 3 numbers: the row proportions, the column proportions and the totalt number of observations. Since the total number of number in your table is 4, and 3 were already known before you started to compute the chi-square statistic, the degrees of freedom is 4-3=1

examine associations among variables and tests of differences between groups. Parametric and Nonparametric Statistics In the world of statistics, distinctions are made in the types of analyses that can be used by the evaluator based on distribution assumptions and the levels of measurement data. For example, parametric statistics are based on the assumption of normal distribution and randomized sampling that results in interval or ratio data. The statistical tests usually determine significance of difference
