Interpolating missing data

[Arbnor Gashi]

Can we interpolate missing data for central bank policy rate by using leading rate or any other economic variable, and if so how can we do that in Stata?

Arbnor:
you may want to take a look at -ipolate-.
That said, methodologically speaking, it would be more advisable to diagnose the mechanism underlying the missingness and go -mi- (if feasible).

[Arbnor Gashi]

I don't get what you meant by

missingness

mechanism. Could you please explain it a bit? Or could you please show me an example?

[Carlo Lazzaro]

Arbnor:
see -help mi_glossary-: MCAR; MAR; MNAR.

It seems puzzling that central bank policy rate is the kind of variable that would ever be missing.....

[Arbnor Gashi]

Yes, of course. Most of websites that I have seen so far have missing cbr rate for developed countries before 1970 and a lot missing data for developing countries.
