WebFeb 6, 2016 · Var1 and Var2 are aggregated percentage values at the state level. N is the number of participants in each state. I would like to run a linear regression between Var1 and Var2 with the consideration of N as weight with sklearn in Python 2.7. The general line is: fit (X, y [, sample_weight]) Say the data is loaded into df using Pandas and the N ... WebFeb 1, 2024 · 1. You need to check your data dimensions.
