"Slope - linear regression"
Learner III
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

if you make a linear regression, the slop is the same on each data point, since it is linear...You can read this slope from the table of coefficients.
If you want to convert dates try using the Date to Numerical Operator.
