in addition to Nick's comments on graph in version 8, I think a reminder that one can always use the version 7 syntax by starting with the command -gr7- is important. This is especially true if you are in an analytic mode (rather than looking for a publication quality graph) since gr7 is MUCH faster than the version 8 graphs. Rich Nick Cox wrote:

Actually, there's a wrinkle here

which I think is worth spelling out.

Presuming that your response variable is y and the others are covariates, the command

. graph matrix x1 x2 x3 x4 y

ensures that the bottom line of graphs all have y as vertical axis variable and the various x* as horizontal axis

variables. You may agree with me in preferring this arrangement to that produced by

. graph matrix y x1 x2 x3 x4

So mention the response _last_ (clearly, the opposite of what you must

do with e.g. -regress-).

When you are unsure of command names,

. search graph matrix

(e.g.) will point towards them.

After a regress command with -robust- and -cluster- option I used a Ramsey test (-ovtest, rhs) which suggested that there are higher order trends, but omitted from the regression model. I was trying to use a scatterplot matrix to look at higher order trends. As I remember in Stata 7, the command for this was: Graph y x1 x2 x3 x4, matrix* * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
