This issue is about Spreadsheet input.

Supporting more distribution families (other than piecewise uniform) would be an obvious next step.

Input format

To do this in Excel, I would probably introduce a new format:

a cell containing the distribution family as as string
the next n (maybe up to n=4? ) cells to the right would define the distribution parameters. e.g. for a normal distribution the program would expect the mean, then the sd. This means these cells have a different interpretation depending on the family, which would definitely make the spreadsheet less readable 😞

If you think of an idea with better UX I'd love to hear it!

Choice of families

Which distribution families would be most useful to you? I would definitely provide the obvious ones like normal, lognormal, and beta.
