Confidence interval of predicted value

WebJun 14, 2024 · Prediction Intervals Method 1: RMSFE The first method that we can use is called RMSFE (root mean squared forecasting error). RMSFE is very similar to RMSE. The only difference is that RMSFE has to be calculated on residual terms from predictions on unseen data (ie. Validation or Test set). Web= Sensitivity × Prevalence + Specificity × (1 − Prevalence) Sensitivity, specificity, disease prevalence, positive and negative predictive value as well as accuracy are expressed as percentages. Confidence intervals for sensitivity, specificity and accuracy are "exact" Clopper-Pearson confidence intervals.
