R: Calculate and interpret odds ratio in logistic regression

Webbb. To show that π = 0.50 when LI = 26.0, we look at the row where LI = 26 and find the proportion of cases that achieved remission, which is 1.000. We can then use the logistic regression equation to calculate the predicted probability of remission for LI = 26: logit(π) = β0 + β1 LI logit(π) = β0 + β1(26) logit(π) = β0 + 26β1 WebbSo, the predicted values from the above model, i.e. the log odds of the event, can be converted to probability of event as follows: P i = 1 − ( 1 1 + e i z) This conversion is achieved using the plogis () function, as shown below when we build logit models and predict.
