How to extract fitted line equations?
I have 60 Bivariate plots and each plot is fitted with a line. How can I extract the line parameter using script?
For example, the fitted line is y=ax+b, how can i get a and b and save them into variables. When i try to use tree structure, it only shows the tree for first plot, and the command to grab values from boxes doesn't work.
Anyone knows how to do that? thanks in advance!
