maybe try using a very small dataset and debug that?

one where you know what correlation coefficients/etc you would expect

Also, maybe fix your formatting/indentation

you can do that with Ctrl+Shift+F in Eclipse or Ctrl+Alt+L in IntelliJ I think

i am using a small data set 😭 its like 5 users ratings of 3 songs, and the other input file is the songs, two of the users didnt rate two songs, my prediction is off by a smidge, so im assuming something is wrong with the math but i cant figure out what, where its supposed to be a 5 and 4 i get a 4 and 1

this for sure the code is messy apologies

[onyx geyser]

so you can calculate it manually and compare all intermediate results?

as I said, your IDE can format the code automatically
