calc_mROC_stats	Calculates the absolute surface between the empirical and expected ROCs
calc_NB_moments	Calculates the first two moments of the bivariate distribution of NB_model and NB_all
calibration_plot	Title Create calibration plot based on observed and predicted outcomes.
dev_data	model development data
evpi_val	EVPI (Expected Value of Perfect Information) for validation Takes a vector of mean and a 2X2 covariance matrix
gusto	Anonymized data from the gusto trial
mAUC	Takes in a mROC object and calculates the area under the curve
mROC	Calculates mROC from the vector of predicted risks Takes in a vector of probabilities and returns mROC values (True positives, False Positives in an object of class mROC)
mROC_analysis	Main eROC analysis that plots ROC and eROC
mROC_inference	Statistical inference for comparing empirical and expected ROCs. If CI=TRUE then also returns pointwise CIs

odds_adjust	Title Update a prediction model for a binary outcome by multiplying a fixed odd-ratio to the predicted odds.
pred_summary_stat	Title Estimate mean and variance of prediction based on model calibration output.
val_data	model validation data
