From: "jiang zhigang" jiangzhigangchn@hotmail.com Subject: [NMusers] Hi,dear all ,some new questions occur ! Date: Fri, 11 Aug 2006 13:26:34 +0800 Dear all, I appreciate your warmhearted help! Now,I have some new problems which are easy to you! Please help me ! When I read the NONMEM User Guide,I was puzzled by these matters: 1. In the book,there are many index plots. Now,I notice there are many characters(such as K,B,C,A,E,etc.) and numbers(such as 2,3,6,9,etc.) appears in the index plots! The approximate delineation as follow: AMT VS. ID ...................................................................................... . . 5 K * * . 3 B . 3A * . 3 A * . 6CB * * . 3 C * . 86C * * * . In addition,I don't understand why there are some characters such as G,F,H in the Index plot for weight(WT)?And,what's the meaning of them? What's the meaning of 3 or 2 in the plot of DV VS. ID? 2.The guide said:"Many points lie along the line AMT=0,where one sees integers 5,3,3,6,etc,as one proceeds along the ID axis,each integer indicating the corresponding number of points over-plotted at that location." My question is why there are so many overlap points in the index plot for AMT VS. ID?The picture' x-axis is AMT and its y-axis is ID,and the dot is corresponding to x-coordinate(AMT) and its y-coordinate(ID),so how does the points over-plotted ? Thank you very much!
