The third LSMEANS statement sets the coefficient for x1 equal to 1.2 and leaves it at for x2, and the final LSMEANS statement sets these values to … In a sense, LS-means are to unbalanced designs as class and subclass arithmetic means are to balanced designs. Node 13 of 24. Multiple effects can be specified in one LSMEANS statement, or multiple LSMEANS statements can be used, but they must all appear after the MODEL statement. Thanks in advance and let me know if anything is unclear! Node 14 of 24 . Is there any option within PROC PHREG procedure will output the hazard ratios I need from above question? for the model in PROC PHREG, a best tool for initial screening. NOTE: The PHREG procedure generated the model item store WORK.PREDICTEDVALID. The following statements print out the observations in the data set Pred1 for the realization LogBUN=1.00 and HGB=10.0: . As an example, suppose that you intend to use PROC REG to perform a linear regression, and you want to capture the R-square value in a SAS data set. MODEL Statement ... PROC PHREG finds all the variables that interact with the variable of interest. LSMESTIMATE Statement Tree level 4. BASELINE Statement ... Table 86.8 summarizes the options available in the LSMEANS statement. The MIXED procedure picks up the LSMESTIMATE statement and the SLICE statement, and the PHREG procedure picks up the ESTIMATE, LSMEANS, LSMESTIMATE, and SLICE statements. PROC PHREG Statement Tree level 4. ASSESS Statement Tree level 4. ... LSMEANS Statement LSMESTIMATE Statement MODEL Statement OUTPUT Statement Programming Statements STRATA Statement SLICE Statement STORE Statement TEST Statement WEIGHT Statement Words in italic are new statements added to SAS version 9.22. proc print data=Pred1(where=(logBUN=1 and HGB=10)); run; As shown in Output 86.8.2, 32 observations represent the survivor function for the realization LogBUN=1.00 and HGB=10.0. For example, LSMEANS does the job in PROC MIXED, LOGISTICS, and other procedures. The documentation for the procedure lists all ODS tables that the procedure can create, or you can use the ODS TRACE ON statement to display the table names that are produced by PROC REG. You can use the STORE option to save the Phreg information and then Proc PLM to score the data pointing to that saved information. For example, proc glm; class A B; model Y=A B A*B; lsmeans A B A*B; run; LS-means are displayed for each level of the A, B, and A * B effects. Handily, proc phreg has pretty extensive graphing capabilities.< Below is the graph and its accompanying table produced by simply adding plots=survival to the proc phreg statement. 2. diff; As in the GLM procedure, LS-means are predicted population margins —that is, they estimate the marginal means over a balanced population. The LSMEANS statement computes least squares means (LS-means) of fixed effects. Node 2 of 24 . The first observation has survival time 0 and survivor function estimate 1.0.

For example, the GENMOD procedure now offers the EFFECTPLOT, LSMESTIMATE, and SLICE statements, and its LSMEANS statement has been updated with additional features. If the BAYES statement is specified, the ADJUST=, STEPDOWN, and LINES options are ignored. However, for the first LSMEANS statement, the coefficient for x1*x2 is , but for the second LSMEANS statement, the coefficient is .
