Software for Simple Linear Regression

#1
Hi!

I am looking for a free or fairly inexpensive software package to perform simple linear regression (time series) and exponential smoothing tests. I need to test about 100 data points (i.e., years). Suggestions?

Thank you!

Pretty much. I believe it may have a model fit option for quadratics - I can't recall if that included smoothing. Though I think data can just be transformed to incorporate smoothing.

R and Python are software options as well, but traditionally thought to be more technical.
