ok, but i have no idea what is the problem i can't get mode, skewness and uncertainty series, or in first create it in the workfile, and next use the Add-in.
(*)the prg calcquant i use it in the first to generate mode, skewness and uncertainty.

I'm not sure what there is to explain. In order to calculate a Bank of England style fan chart, you need to have the mode, uncertainty and skewness values of your forecast.

The add-in does not calculate those for you, it uses them as inputs.

Hi Gareth,

how do i use the fanchart addin using program code?

i tried

Code: Select all

cpi.fan mode uncertainty skewness

but then the option menu came up?

can you also give the precise link to where BoE explains the skewness and uncertainty series?

There is no command line interface to this add-in. You're better off stealing the source code and adding it to your own program to suit your needs.

This paper (although not a BoE paper) explains the methodology well:
