Predicting using linear regression
WebAug 3, 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. According to R, those coefficients are: WebMar 3, 2024 · There is something very complex going on when we apply linear regression to our data and try to predict outputs. But we just need to pass our pre-processed data into our model and all the complex calculations of machine learning will happen under the hood. So next, we need to fit the data to our linear regression model. model.fit(M_train, n_train)
