Summary Methods For Objects in the Class mixedAn (Mixed Analysis)

Prints a summary table for the results of the mixed analysis for the economic evaluation of a given model.

Usage

# S3 method for mixedAn
summary(object, wtp = 25000, ...)

Arguments

object: An object of the class mixedAn, which is the results of the function mixedAn(), generating the economic evaluation of a set of interventions, considering given market shares for each option.
wtp: The value of the willingness to pay chosen to present the analysis.
...: Additional arguments affecting the summary produced.

Value

Produces a table with summary information on the loss in expected value of information generated by the inclusion of non cost-effective interventions in the market.
