It takes just 2 minutes to sign up (and it's free!). The poisson cdf continued fractions for the tails of the poisson distribution are old and well known - I really should find references to these. If you don't mind running VBA functions, http://members.aol.com/iandjmsmith/Examples.xls has replacements for all of Excel's probability functions, and appears to be quite good in accuracy and working range.

Many would appreciate credit where credit is due. https://support.microsoft.com/en-us/kb/828313 The algorithms MS chose for distribution formulas give limited accuracy over a limited working range, and the inverse functions are even worse.

The error is inconsistent as there appears to be no upper limit on the D of F value which returns the error. Chi Square Distribution Excel Syntax The syntax for the CHIINV function in Microsoft Excel is: CHIINV( probability, degrees ) Parameters or Arguments probability The probability for the chi-squared distribution. Need more? If the search has not converged after 100 iterations, the function returns the #N/A error value.

You need the quantile function, not the density function, and you don't want the inverse of the chi-squared distribution (although the confusion seems natural coming from Excel's function). Consider: > qchisq(p=0.2, df=2, lower.tail=FALSE) [1] 3.218876 Furthermore, according the the documentation, dinvchisq() is the density function (the height of the pdf at a given quantile) of the inverse of the Advertisements Latest Threads Thersa May gets told off TriplexDread posted Oct 5, 2016 at 9:45 PM Google announced an iPhone, a Gear VR, an Echo, and an Eero Becky posted Oct EG.
