Dear all,
I would like to fill the missing value in var1 based on the trend of the
same variable (=var1) instead of using additional independent variable.
However, "ipolate" requires an independent variable. How can I fill the
missing value based on the trend of the variable itself? I would like to use
exponential decay for var1, but a linear trend is also fine.
id var1
1 45
2 37
3 32
4 31
5 17
6
7 3
8 1
Thank you in advance.
Mike.
