It is a method of updating b 0 and b 1 values to reduce the MSE. The idea behind this is to keep iterating the b 0 and b 1 values until we reduce the MSE to the minimum. To update b 0 and b 1, we take gradients from the cost function.

Linear regression is a linear model , e.g. a model that assumes a linear relationship between the input variables (x) and the single output … Simple linear regression is a parametric test, meaning that it makes certain assumptions about the data. These assumptions are: 1. Homogeneity of variance (homoscedasticity): the size of the error in our prediction doesn’t change significantly across the values of the independent variable. 2. … See more When reporting your results, include the estimated effect (i.e. the regression coefficient), standard error of the estimate, and the p value. You … See more To view the results of the model, you can use the summary()function in R: This function takes the most important parameters from the linear model and puts them into a table, which looks like this: This output table first … See more No!
