WebbA 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. Webb31 mars 2024 · regression=function (num,x,y) { n=num b1 = (n*sum (x*y)-sum (x)*sum (y))/ (n*sum (x^2)-sum (x)^2) b0=mean (y)- b1*mean (x) return (c (b0,b1)) } With this, you can get a vector containing your b0 and b1.

The linear equation is: y = B0 + B1*x. Here, y is the predicted variable. B0 is the intercept — the predicted value of y when x is 0. In this example, you can see that when x is 0, the value of y is 75. WebbThe simple linear regression model for nobser-vations can be written as yi= β 0 +β 1xi+ei, i= 1,2,··· ,n.
