Function "filter" in FAVAR

Hello,

I have a question about the function "filter" available in the FAVAR section: What is the algorithm used to generate the missing observations? Do you have a reference I can read to understand it?

So far, I understand that (tell me if it is wrong!) that you handle data with different frequencies by considering the low-frequency variable as a high-frequency one with missing observations. The Kalman filter and smoother is then applied to estimate the missing observations. The dynamics of the low and high-frequency series are jointly analyzed.

Thanks,
Gabriel
