Witryna1 lis 2011 · Points (black arrow) on the receiver-operating characteristic curve represent the possibility levels generated from the logistic regression analysis that was used to select the optimal cut point. A predicted probability of 0.23 provided a sensitivity of 88.5% and a specificity of 79.1%. Discussion WitrynaThe logistic regression model is a probability model. It is inappropriate to think of cutoffs when using it. The use of a cutoff for a decision threshold is separate from the modeling process and makes a strong assumption that the cost/loss/utility function (consequences of decisions) is the same for all observations/subjects.

Witrynaknown as logistic regression or logit model. Given a vector of application characteristics x, the probability of default p is related to vector x by the following equation: Logistic regression provides a method for modeling a binary response variable, which takes values 1 and 0 by mapping the data on a logit curve (Figure 1).

WitrynaGetting the "optimal" cutoff is totally independent of the type of model, so you can get it like you would for any other type of model with pROC. With the coords function: coords (g, "best", transpose = FALSE) Or directly on a plot: plot (g, print.thres=TRUE) Now the above simply maximizes the sum of sensitivity and specificity.
