If you would want to e.g. have very low FPR you would want to choose a lower threshold instead. After choosing a threshold, you can use the predicted class probabilities to immediately determine the predicted class:

WebThe threshold parameter γ, provides an estimate of the earliest time a failure may occur. The threshold parameter locates the distribution along the time scale and has the same units of time, such as hours, miles, or cycles. ... Choose a distribution with a threshold parameter (3-parameter Weibull, 2-parameter exponential, 3-parameter ... WebCalculating Weibull Parameters. There are three standard parameters for the Weibull distribution: Location, Scale, and Shape. The Location parameter is the lower bound for the variable. The Shape parameter is a number greater than 0, usually a small number less than 10. When the Shape parameter is less than 3, the distribution becomes more and ...
WebThe Create Threshold operator is used for creating a threshold. The threshold parameter is set to 0.700 and the first class and second class parameters are set to 'negative' and 'positive' respectively. A breakpoint is inserted here so that you can see the threshold in the Results Workspace. This statement in the Results Workspace explains ... WebMay 11, 2016 · Generate the ROC curve and choose the threshold within the training data, but then report accuracy, sensitivity, etc. when using this threshold to make predictions in the test data. AUC is not a great metric, but if you want it (and you don't want it to be optimistically biased), generate another ROC curve for the test data and report the AUC ...
WebMar 26, 2024 · The Akaike information criterion is calculated from the maximum log-likelihood of the model and the number of parameters (K) used to reach that likelihood. The AIC function is 2K – 2 (log-likelihood).
