Unsure Calculator

I love this! As a tool for helping folks with a good base in arithmetic develop statistical intuition, I can't think offhand of what I've seen that's better.

I like this! In the grand HN tradition of being triggered by a word in the post and going off on a not-quite-but-basically-totally-tangential rant: There’s (at least) three areas…

> The UI is ugly, to say the least. I actually quite like it. Really clean, easy to see all the important elements. Lovely clear legible monospace serif font.

The ASCII art (well technically ANSI art) histogram is neat. Cool hack to get something done quickly. I'd have spent 5x the time trying various chart libraries and giving up.

Would be nice to retransform the output into an interval / gaussian distribution ``` Note: If you're curious why there is a negative number (-5) in the histogram, that's just an…

On the whole it seems like a nice idea, but there's a couple of weird things, such as: > Note: If you're curious why there is a negative number (-5) in the histogram, that's just…

This is super cool. It seems to break for ranges including 0 though 100 / -1~1 = -3550~3500 I think the most correct answer here is -inf~inf

https://qalculate.github.io can do this also for as long as I've used it (only a couple years to be fair). I've got it on my phone, my laptop, even my server with apt install…

It's all computed in the browser so yeah, it's JavaScript. Still, 8 seconds is a lot -- I was targeting sub-second computation times (which I find alright).

Feature request: allow specifying the probability distribution. E.g.: ‘~’: normal, ‘_’: uniform, etc.

Cool! Some random requests to consider: Could the range x~y be uniform instead of 2 std dev normal (95.4%ile)? Sometimes the range of quantities is known. 95%ile is probably fine…

Is there a way to do non-scalar multiplication? E.g if I want to say "what is the sum of three dice rolls" (ignoring the fact that that's not a normal distro) I want to do 1~6 *…

If I am reading this right, a range is expressed as a distance between the minimum and maximum values, and in the Monte Carlo part a number is generated from a uniform…

https://www.getguesstimate.com/ is this, as a spreadsheet

This reminds me of https://www.getguesstimate.com/ , a probabilistic spreadsheet.

See also Guesstimate https://getguesstimate.com. Strengths include treating label and data as a unit, a space for examining the reasoning for a result, and the ability to replace…

I have written similar tools - for command line, fermi: https://git.nunosempere.com/NunoSempere/fermi - for android, a distribution calculator:…

The authors of Guesstimate are now working on https://www.squiggle-language.com/ Someone also turned it into the https://github.com/rethinkpriorities/squigglepy python library
