### Temporal disaggregation procedures .....

Below you can find Temporal disaggregation procedure using Denton, Cholette, Fernandez, BFL, Chow-Lin methods as a subroutine in EViews. Copy and paste the code into your program window to execute. Below I posted also instruction hot to use it. Please feel free to modify and/or improve it.
This procedure was written for Eviews before multi frequency Workfiles were introduced, so all input series are in one frequency. Procedure is working in target frequency, i.e. when you disaggregate series from yearly to quarterly values input series are quarterly. Annual series is technically uniformly disaggregated. Low frequency series is again aggregated (by sum) to original frequency inside the procedure.

Inputs are series (not vectors), before using procedure, you have to define result series (high frequency) and equally distributed low frequency one. In current version I do it using link series. But it can be also done outside Eviews by dividing low frequency number by frequency.
