# Todo List ## PHPExcel_Calculation ### PHPExcel_Calculation_Functions::BINOMDIST() Cumulative distribution function ### PHPExcel_Calculation_Functions::CRITBINOM() Warning. This implementation differs from the algorithm detailed on the MS web site in that $CumPGuessMinus1 = $CumPGuess - 1 rather than $CumPGuess - $PGuess This eliminates a potential endless loop error, but may have an adverse affect on the accuracy of the function (although all my tests have so far returned correct results). ### PHPExcel_Calculation_Functions::LOGINV() Try implementing P J Acklam's refinement algorithm for greater accuracy if I can get my head round the mathematics (as described at) http://home.online.no/~pjacklam/notes/invnorm/ ## Math_Stats ### Base::interquartileMean() need to double check the equation ### Base::percentile() need to double check generality of the algorithm ### Base::quartileSkewnessCoefficient() need to double check the equation ### Base::quartileVariationCoefficient() need to double check the equation Documentation generated on Mon, 11 Jan 2010 08:19:24 +0100 by phpDocumentor 1.4.1
