Hi,

I saw some forecast functions in LEAP ( e.g. LinDataTrend, LinForecastBY). I wonder how LEAP calculates R2 of these linear regression expressions. I could not see any choice besides Std and Var.

Could you give some example?

Thanks,
Hasret

Hi Hasret,

You can have a look at the RSquared() function:

http://www.energycommunity.org/WebHelpPro/Expressions/RSquared.htm

but at the time of posting this reply, we've identified a few issues with it (not to mention, we hope to soon update/clarify the documentation for it).

Currently, the RSquared function only takes a time series of year and value pairs, like this:

RSquared(2010,10,2020,20,2030,30)

and generates the R2 value (the coefficient of determination) assuming a *linear* fit through the data. We will be working to expand its usefulness, as well as improve documentation in the coming weeks. Thank you for bringing it to our attention!
