What books would help understand the math behind firecalc?

[jIMOh]

I'd like to understand more of the math that goes into calculators like this. Are their any books which show the logic, returns or math behind the calculations?

Did you try reading the original trinity / Bergen papers?

Is the calculator only based on the trinity study?

On this page someone mentions that Firecalc uses the Shiller Data Set.
How do dividends figure into things like firecalc? : financialindependence

Shiller data in .xls format is very east to locate.

does fire calc convert the data to annual returns, or just use the differences in the S&P 500 composite?

Sorry, I can't help you with that answer.

Raw data I found

Historical Returns

Looks like the SP500 includes dividends, so now all you need is CPI data.

All of the data is here in an Excel workbook on yale's web, if that is more convenient.

Edit, a higher link if necessary:

I think ******** (similar to firecalc) has source code available on github (javascript).

If I were looking to replicate the analysis, I'd probably do this in R or matlab.
