• Create correlation matrix

  I need to create a correlation matrix  to use for some simulations.  I want all the off-diagonal elements of the correlation to be the same value.  Here is a simple script that does that, but I was wondering if there was a simpler way to do it.     names default to here(1); // create correlation matrix with specified correlation k=5; r=0.9; corr_matrix=J(k,k,r); // diagonal elements equal to 1 by ...

• Adding connecting letters ABOVE data points of a line graph

  I have letters from a connecting letters report, my means, and SEMs in columns of a new data table. I've created a line graph with points.  As suggested in previous discussion posts I've tried "Set shape column" but as you can see the letters are behind the line and so unreadable. I would like to add the letters as labels floating above the points (so they are legible). How can I adjust what posit...
