WebbAnalogous plots for logistic regression. The logistic regression model says that the mean of Y i is μ i = n i π i where log ( π i 1 − π i) = x i T β and that the variance of Y i is V ( Y i) = n i π i ( 1 − π i). After fitting the model, we can calculate the Pearson residuals: r i = y i − μ ^ i V ^ ( Y i) = y i − n i π ^ i n i π ^ i ( 1 − π ^ i) Webb9 aug. 2024 · When we create a ROC curve, we plot pairs of the true positive rate vs. the false positive rate for every possible decision threshold of a logistic regression model. How to Interpret a ROC Curve. The more that the ROC curve hugs the top left corner of the plot, the better the model does at classifying the data into categories.
