Create simple linear regression model
WebA simple linear regression model is a mathematical equation that allows us to predict a response for a given predictor value. Our model will take the form of ŷ = b 0 + b1x where b0 is the y-intercept, b1 is the slope, x is the predictor variable, and ŷ an estimate of the mean value of the response variable for any value of the predictor variable. WebNov 4, 2015 · Just focus on the model: y = 200 + 5 x This formula is telling you that if there is no x then y = 200. So, historically, when it didn’t rain at all, you made an average of 200 sales and you can...
