Consider a binary outcome response variable
The logistic model is formally given by:-
In the two texareas below, the first (narrow) one on the left has the response variable
To run the algorithm once the values have been entered in the textareas, simply click on the "Estimate model parameters" button. A plot indicating algorithm convergence will be updated (showing the increase of the log likelihood function), and could be useful in specifying the number of iterations needed for the Newton-Raphson algorithm. Finally, the Receiver Operating Characteristic (ROC) plot will be generated. For the ROC, a black line of gradient 1 will be generated as reference.
