P(multiple)=3 If the difference in R^2 values between the simple and multipleregressionis “big” and the p-values is “small”, then adding tail length to the model is worth the trouble. Comparing simple and multiple regression in R For simple regression, we will focus on how well weig...
What Does the Multiple Linear Regression Model Tell Us? Now that we have built the model, the next step is to check the assumptions and interpret the results. For simplicity, we will not cover all the aspects. Distribution of the model residuals This can be shown in R using the hist()...

We know that cost functions can be used to assess how well a model fits the data on which it's trained. Linear regression models have a special related measure called R2(R-squared). R2is a value between 0 and 1 that tells us how well a linear regression model fits the data. When...
