sas retain statement in R or fitting differene equations in NLS
...retain/ *statement.
For people that want to read complicated explanations to help me:
I have a system of two equations written as difference equations here.
To boil it down. I have a dataframe with three variables y, X1, X2 which
are measured. Now, I want to estimate a model which says y=
yhat+epsillon as in standard nonlinear regression. Where yhat is the
predicted value of y.
yhat can be calculated as follows:
# This code illustrates how I could simulate the expected values of y if
I knew the values of the parameters tau and b.
# but in reality I would like to estimate them.
# code is for i...
