NettetLogistic regression is a special case of the generalized linear regression where the response variable follows the logit function. The input of the logit function is a probability p, between 0 and 1. The odds ratio for probability p is defined as p/ (1-p), and the logit function is defined as the logarithm of the Odds ratio or log-odds. Simple linear regression is a parametric test, meaning that it makes certain assumptions about the data. These assumptions are: 1. … Se 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, which … Se mer No!
