I am trying to calculate individual predicted probabilities from a logistic regression model with spss (to describe how a individual probability could be calculated from my model. A logistic regression model makes predictions on a log odds scale, and you can convert this to a probability scale with a bit of work.

The General Form Of The Command Is:

The code below generates the predicted probabilities using a. P ( y i) is the predicted probability that y. X = scale (data) logreg = logisticregression () #fit the model logreg.fit (x,y) #print the score print (logreg.score (x,y)) after scaling the.
