Hi all,   I am trying to understand why in the example for GEE (page 3) the Type 1 option is being used rather than the Type 3 option.    https://support.sas.com/documentation/cdl/en/statug/63962/HTML/default/viewer.htm#statug_genmod_sect064.htm   Also it seems to contradict with what is described here: https://support.sas.com/documentation/cdl/en/statug/63033/HTML/default/viewer.htm#statug_genmod_sect034.htm   Which says "This type of analysis is not available for GEE models, since the deviance is not computed for this type of model."   Thanks, Doug   ...

Hi All,   So I have data as follows:  Time = X  Result = Y   Time (Months)   Result 0 7.17 3 5.98 6 7.31 12 73.87 18 80.92 30 39.11 36 37.93 42 33.3 48 35.2 78 33.26   I need to fit a cubic spline to the data, and then find Y-values for 8 equal time points between 19.2 and 44.4 months. And then do a regression on those 8 data points to find a slope.   I have been playing around with proc glmselect, and I get 5 knots and their parameters...but I can't seem to apply the equation correctly after the first knot, I am not sure how to get SAS to show me the other parts of the predictive equation (i.e. the second intercept)   This is how far I got: ods select ANOVA ParameterEstimates SplineKnots TPFSplineDeatils; ods output ParameterEstimates=param SplineKnots=spline ; proc glmselect data=patient1; effect spl = spline( time/ details naturalcubic basis=tpf(noint) knotmethod=percentiles(5) ); model result = spl / selection=none ; /* fit model by using spline effects */ output out=SplineOut predicted=fit ; /* output predicted values for graphing */ quit; ...

So currently I am assessing agreement between two evaluators. They are assessing disease response and the table would like below:                      Evaluater 2  CR     CRc      CRi        PR        SD       PD Evaluater 1 CR CRc CRi PR SD PD   To calculate a weighted Kappa is assigned an Ordinal value to each response: 1, 2, 3, 4, 5, 6. Which sas that uses the following weights as default: 1.00, 0.8, 0.6, 0.4, 0.2.   However, I would really like for CRc and CRi to have the same weights for distance from CR. Does anyone know how I should reorder the ordinal values if even possible, my issue is that they can't have the same ordinal value --- is the only way to combine CRc & CRi? I don't know if that would be clinically meaningful. ... View more

Looking for general information about 1-sided CMH tests. Also if anyone has any code with regards to this test that would be helpful.   can use variables strata*treatment*outcome. ... View more
