How to draw linear regression line
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. … Ver más 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, … Ver más No!
