Witryna3 lis 2024 · We’ll use the R function glmnet () [glmnet package] for computing penalized logistic regression. The simplified format is as follow: glmnet (x, y, family = "binomial", alpha = 1, lambda = NULL) x: matrix of predictor variables y: the response or outcome variable, which is a binary variable. family: the response type. WitrynaA logistic regression (or any other generalized linear model) is performed with the glm () function. This function is different from the basic lm () as it allows one to specify a statistical distribution other than the normal distribution. glm(formula, family = ???, # this argument allows us to set a probability distribution! data, ...)

WitrynaThe only other difference is the use of family = "binomial" which indicates that we have a two-class categorical response. Using glm () with family = "gaussian" would perform the usual linear regression. First, we can obtain the fitted coefficients the same way we did with linear regression. coef(model_glm) WitrynaThe default link for the Binomial family is the logit link.
