Drawing simple path diagram

[Giorgio Piccitto]

Dear all, I have an apparent simple question. I would like to graphically visualize my analytical strategy with a simple path diagram like the one attached. Is that possible to build up something similar with Stata? I am not so expert of the graph editor, and I would not know hot to proceed.

Thanks a lot, best, G

There is a worked example here: http://www.maartenbuis.nl/workshops/...l#slide39.smcl

Dear Maarten, thanks a lot, I'll play around with that example to obtain something that may be useful for me.

Just one thing: how should I draw the box around the labels?

Thanks a lot, G

Dear all, thanks a lot for your suggestions. I nearly realized what I need with the following code:

There is only one missing thing, that I am not able to control. Some of the arrows are not filled in black, but this option it is specified for all of them, do you know why this happen? Attache the image that I have.

Thanks a lot, G

Dear all,

anyone has some clue on why the same option -black- does not apply to all the arrows (in filling them)?

Sorry but I am going crazy about that.
