When I implement:
use C:\Users\CONDE\Desktop\simulation\denton1.dta

denton fpi using denton3, interp(ip) from(C:\Desktop\denton2.dta)
generate(monthly_fpi)

I receive following message:

denton currently requires low-frequency data to be yearly or quarterly.
r(322);

or

ip must be available for entire selected sample.
r(198);
Thanks in advance for any help
