"Slope - linear regression"
Hi!
I am new in working with RM, and I need help how to perform two things, to code days like 1,2,3... and to calculate slope per each case.
I have cases and their amount paid daily. I need to have something like this from data id, date, amount:
id Date Amount x y
case1 01.10.2010 322 1 322
case1 10.11.2010 100 2 100
...
case2 03.08.2010 120 1 120
case2 10.09.2010 300 2 300
case2 11.11.2010 240 3 240
...
I need slope of linear regression per each case, like in excel.
I couldn't find how to do this in RM
