Dear Rick: Thank you for your tremendous help! This "calibration plot" is an question in my assignment of a master-degree university course. To the best of my knowledge, your solution is the only, and THE BEST, resource that is available online as of now. In my homework, I cited your instructions and wrote: "The solution and the codes were developed under the guidance of, and virtually by, Mr. Rick from the SAS Institute. Web link listed below. https://communities.sas.com/t5/forums/replypage/board-id/sas_graph/message-id/11641" The final graph is enclosed in the attachment for other SAS users' reference. This calibration plot is widely used to illustrate the performance of a "risk prediction model" in the medical land. It compares the predicted risk with the observed risk by level of the predicted risk. Statistically, it is also a visualization of the "Hosmer-Lemeshow test" that examines the extent to which the predicted values produced from the statistical model match the observed values obtained from the real world. Many thanks again! Ning
