I am In SAS®, the LIFETEST procedure compares the survivor function between study arms, and the PHREG procedure estimates the effect of study treatments on hazard rates. The following code segment accomplishes this: Hello, I have two datasets out1 and out2 which are sorted by LOB MAIN_INSRR_CO_NBR PROVINCE CIEDISTR Each dataset has 40 observations. one compare=proclib. Generating reports was also added through the PUT and FILE statements. It will present the basic structure of PROC COMPARE, how the procedure can be augmented with a few simple statements and options, and how to use this versatile procedure to make comparisons within a single data set or across data sets. To do this the input data sets need to be sorted on these variables, and in PROC COMPARE the variables will be used on the ID statement. When you use an ID variable, PROC COMPARE uses the values of the ID variable to determine which observations to compare. In the example, we will be comparing before and after changes versions of a mock Visits data set using the unique combinations of variables Site, SubjectID, and VisitType. For example, the statement “input name : $7. Given the input parameters, the TTEST procedure calculates the test statistics, the corresponding p-value, and confidence intervals. Among the aboved-mentioned variables, I have N and FTPREM which are numerical variables.
