Since these calculators can solve for any variable, many of the CDF calculators can also calculate the inverse functions.
Statistical distribution are used in many forms. Most of these Function Calculators are JavaScript functions "wrapping" a c1 function (See CALC 1 c1 Object Reference, Probability and Statistics Functions) that is compatible with the spreadsheet function for that distribution.
If you think that another Function Calculator is needed for a distribution, please contact us.
Since CALC 1 is customizable, you can also consider customizing an existing Function Calculator by duplicating an existing Function Calculator.
For example, the body of the Normal Dist CDF Function Calculator is:
return c1.normdist(x, mean, sd, 1);
and the body of the Normal Dist CDF Upper Tail Function Calculator is:
return 1  c1.normdist(x, mean, sd, 1);
So if you have experience using the spreadsheet functions, modifying Functions Calculators to fit your requirements is something to consider.
