Nick, Thanks so much for your explanation. I appreciate you.

Hence consult [G] graph matrix and its references for more detail. A .pdf copy is included with your Stata. But the main idea is very simple. A scatterplot matrix is just a table of scatter plots such that the same y variable is on each row and the same x variable is on each column. Thus you can add to the interpretation of each individual plot some sense of how each data point relates to others, for example, by identifying outliers on either y or x axes and tracing them from plot to plot. A simple tip is to call -graph matrix- such that the response or outcome of most interest (if there is one) is named last; then it will plotted on the last y axis, which will seem natural.

The problem now is that I do not know how to interpret the scatterplot matrix. Is there any reference manual that can be of help? Or can anybody explain this with an example? * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
