mySQL and statistic

[shoa]

Hello all

I have to create a website that will use mySQL database for storing input
data. I can using queries to obtain data from this database. I will use PHP
for enter data or obtain data.

My question is how I can mySQL database for analysing (chi squares,
t-tests....) ?, how can I do that.

Thank you very much

You can use the SQL group functions (e.g. sum(x*x) ) for some
things, but you may well end up needing to fetch all the data
and do the math on the client (PHP) side. You'll need to know
the math formulas for doing stuff like chi squares and t-tests,
as these aren't built in.
