I'm attempting to replicate the functionality of an Excel workbook in Oracle. One of the formulae on the worksheet uses CHIDIST, which "Returns the one-tailed probability of the chi-squared distribution". I can't see a similar function in Oracle anywhere! Am I going to have to write my own CHIDIST function?
Here's a link to Excel's documentation on CHIDIST: http://office.microsoft.com/en-gb/excel-help/chidist-HP005209010.aspx
I've already worked out the Chi Square and Degrees of Freedom.
