Hi, guys   I expand my research of PDF graph to two variables. Here is my code.   data Have; set Sample2(keep=weight inf_weight); run; proc kde data=Have; bivar weight inf_weight / bwm=2 ngrid=250 plots=contour; score data=Have out=Out(rename=(value1=weight value2=inf_weight)); run; proc sort data=Out; by density; run; proc sgplot data=Out; styleattrs wallcolor=white; scatter x=weight y=inf_weight / colorresponse=density colormodel=ThreeColorRamp markerattrs=(symbol=CircleFilled) transparency=0.5; xaxis grid values=(30 to 150); yaxis grid values=(500 to 6000); run; This will produce a scatter plot and the value of PDFs is represented by the color.   If I intend to know the area that corresponds to a probability mass of 95%, how do I get it and mark the area on the graph? I know there is another type of graph called surface plot which uses the volume to represent the probability mass but that's not my consideration. Thanks. ... View more

We use different statistics for continuous and category variables, respectively. We have to use two table statement. Is there any way to show them in one table? Thanks.   Code: proc tabulate data = d202_raw; title 'Summary of patient characterisitcs'; class AF gender smoker CHF DM Stroke Hypertension HFstage hypoalbuminemia RIFLE indication1 CYP2C9 VKORC1 Amiodarone Statin Antiplatelets ; var ageY wt bsa followUp alb1 alb2 alb3 alb4 alb5 ; table ageY wt bsa followUp alb1 alb2 alb3 alb4 alb5 , AF = 'Atrial fibrillation' * (N Mean STD Q1 Q3) all = 'Overall' * (N Mean STD Q1 Q3); table gender smoker CHF DM Stroke Hypertension HFstage hypoalbuminemia RIFLE indication1 CYP2C9 VKORC1 Amiodarone Statin Antiplatelets , AF = 'Atrial fibrillation' * (N colpctn = '%') all = 'Overall' * (N colpctn = '%') ; run; ...
