NettetLinear regression is used for independent continuous outcomes. GLM uses a link function to extend linear regression to other outcomes, such as binary outcomes (eg, logistic regression) or count outcomes (eg, Poisson regression). Linear mixed-effects models allow modeling nonindependent (correlated) continuous outcomes by adding random … Nettet26. aug. 2024 · Linear Regression. We have seen equation like below in maths classes. y is the output we want. x is the input variable. c = constant and a is the slope of the line. The output varies linearly based upon the input. y is the output which is determined by input x. How much value of x has impact on y is determined by “a”.
