I'm learning Proc Genmod at the moment. Novice to modelling as well. I need someone to guide me in interpreting the p roc genmod output although I've some idea to interpret P values. What does the table 'Creteria for accessing goodness of fit' actually explains? From the documentation I understand it explains how our data fits the model, but I don't understand what it actually tells us. Using PROC GENMOD for logistic regression SAS version 6 Note that these notes refer to version 6 of the SAS system. In version 8 it is preferable to use PROC LOGISTIC for logistic regression. See the notes Logistic regression in SAS version 8. Download the handout from seminar I MS Word format. To adapt the concept of ROC curves to the survival setting, various definitions and estimators of time-dependent ROC curves and AUC functions have been proposed. See Blanche, Latouche, and Viallon 2013 for a comprehensive survey of different methods. If the OUTROC= option is specified in a SCORE statement, then the ROC curve for the scored data set is displayed. If you specify ROC statements, then an overlaid plot of the ROC curves for the model or the selected model if a SELECTION= method is specified and for.

I need to estimate sensitivity, specificity, PPV and NPV for clustered data using GEE and programming in SAS. I will use PROC GENMOD with dist=binomial link=log. Hello, I am working on using ROC curves using the Proc Logistic. I have used my ROC curves for what I need but am trying to create a table for 4. A.1 SAS EXAMPLES SAS is general-purpose software for a wide variety of statistical analyses. The main procedures PROCs for categorical data analyses are FREQ, GENMOD, LOGISTIC, NLMIXED, GLIMMIX, and CATMOD. PROC FREQ performs basic analyses for two-way and three-way contingency tables. PROC GENMOD ts generalized linear. Proc genmod is usually used for Poisson regression analysis in SAS. On the class statement we list the variable prog, since prog is a categorical variable. We use the global option param = glm so we can save the model using the store statement for future post estimations. NEW FEATURES OF PROC LOGISTIC IN SAS/STAT® 9.2 SAS/STAT® 9.2 contains valuable additions to PROC LOGISTIC which enhance the visualization of model fit and comparisons between two or more models. The ROC and ROCCONTRAST statements provide this enhanced functionality.

The GENMOD procedure in SAS® allows the extension of traditional linear model theory to generalized linear models by allowing the mean of a population to depend on. ROC CURVE ANALYSIS USING SAS. 2.
