WebbA simple example of regression is predicting weight of a person when his height is known. To do this we need to have the relationship between height and weight of a person. The steps to create the relationship is − Carry out the experiment of gathering a sample of observed values of height and corresponding weight. Simple linear regression is a parametric test, meaning that it makes certain assumptions about the data. These assumptions are: 1. … Visa mer 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, … Visa mer No!
