Glad you like it Glen. I have been working on a new one that has some additional functionality and performance improvements for large datasets using sampling, but I haven’t thought to add t and anova calculations. I’d look into adding it if you would post some links to an explanation of how the calculations are done that you are interested in. I’d gladly accept your code too. ;)

Nice library – simple and to the point.

Planning on giving it a go on a small mobile site for teachers to calculate students-t and anova from arrays.

Before I have a look at coding these – are they in your development t plan?

Cheers

Hi!

Thanks for your work on this library!
I would like to use it, but I don’t understand how to make the calculus.

Would you be so kind to explain how do I use it?

Dave,

I’m glad you found my code useful. I’d love to see about adding more functionality to the library. You can check out my code here (http://code.google.com/p/pseudosavant/source/browse/#svn%2Ftrunk%2FmathStats) and add your functions to it. I will email you about getting you permissions to make commits in the project.

Hey Paul – great work on PseudoSavant! I was in the middle of writing similar functions from scratch and came across PS. Saved a ton of time and I am very thankful.

Here are three statistical functions and two algorithms that would make this library even better than it already is:

SDAM – sum of squared deviations from the array mean
GVF – goodness of variance fit
SDBC – sum of square deviations between classes

Equal Interval Breaks – the most common data classification algorithm
Jenk’s Breaks Optimization – a data classification algorithm for natural breaks in data

I’ll be working on some of these in the next few days — perhaps we can be of help to each other?

Cheers!
Dave
