Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I was wondering if anyone familiar with excel on a mac can help me? Am i able to do polynomial regression with different x's who contain different amounts of elements? I have three columns, one contains 252 elements, another contains 53, and the last contains 12. They are all closing prices of the S&P 500 for days, weeks, and months respectively. Do they have to be equal in order to perform the regression?

Thanks!
