So I've used the ruby source to re-write the ruby statistics2.pnormaldist function in python so we can easily utilise this instead of having to rely on the ruby version. The file pnormaldist.tar.gz available here (http://db.tt/Bx9hmu0) has two scripts in it. pnormaldist.py - my python re-write and a main function to print the output of pnormaldist with values of 0.1 to 0.9 in 0.1 steps pnormaldist.rb. - the original statistics2.pnormaldist ruby function and print statements to print the same output Run like this: python pnormaldist.py ruby pnormaldist.rb to confirm the function works as expected. Change the values in the print functions as required to test other arguments. If happy with the results, we can add the python version to USC's utils.py and use this in the function to create the other function which we can use to calc the Wilson Score cheers Aaron _______________________________________________ Mailing list: https://launchpad.net/~software-store-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~software-store-developers More help : https://help.launchpad.net/ListHelp
