Logistic Regression in R (Odds Ratio) - Cross Validated
WitrynaHow do I run a logistic regression and produce odds rations in R? Here's what I've done for a univariate analysis: x = glm (Outcome ~ Age, family=binomial (link="logit")) And for multivariate: y = glm (Outcome ~ Age + B + C, family=binomial (link="logit")) I've then looked at x, y, summary (x) and summary (y). Is x$coefficients of any value? r WitrynaLogistic Regression with regression splines in R.
