WebbThe OLS regression model is one of most classic methods used for the spatial decomposition of demographic data. The principle of the OLS method is to find the best model by minimizing the sum of the squares of the residuals. Webb3 aug. 2010 · In a simple linear regression, we might use their pulse rate as a predictor. We’d have the theoretical equation: ˆBP =β0 +β1P ulse B P ^ = β 0 + β 1 P u l s e. …then fit that to our sample data to get the estimated equation: ˆBP = b0 +b1P ulse B P ^ = b 0 + b 1 P u l s e.
