In openVA: Automated Method for Verbal Autopsy

Convert the assigned causes to the format expected by vacalibration::vacalibration().

Description

This function prepares the output from codeVA (using the InSilicoVA or InterVA5 algorithms) and/or EAVA for the vacalibration function. The output is a named list, with each element consisting of a data frame with columns for the death ID ("ID") and the assigned CoD ("cause"). The name of each element is the algorithm used to assign the CoD – "insilicova", "interva", or "eava". If the

Usage

prepCalibration(fit, ...)

Arguments

fit	a fitted object from codeVA using either InSilicoVA, InterVA5, or output from EAVA::codEAVA. The EAVA algorithm is assumed if the the argument is a Data Frame (with columns "ID" and "cause").
...	more fitted objects from codeVA using either InSilicoVA or InterVA5, or from EAVA::codEAVA.

Value

a list with each element being a Data Frames that contains variables "ID" and "cause", and the element's name (in the list) is the algorithm name used to assign causes of death (either "insilicova", "interva", or "eava")
