data_completion {MSmix}

Completion of partial rankings with reference full rankings

Description

Deterministic completion of partial rankings with the relative positions of the unranked items in the reference full rankings. Partial rankings with arbitrary patterns of censoring are supported.

Usage

data_completion(rankings, reference_rho)

Arguments

rankings

Integer N\timesn matrix with the partial rankings to be completed in each row. Missing positions must be coded as NA.

reference_rho

Integer N\timesn matrix whose rows represent the reference full rankings to be used to complete the partial rankings.

Details

The arguments rankings and reference_rho must be matrices with the same dimension.

The completion of a full ranking returns the complete ranking itself.

Value

Integer N\timesn matrix with the completed rankings in each row.

Examples

## Example 1. Completion of a single partial ranking.
data_completion(rankings = c(3, NA, NA, 1, NA), reference_rho = c(4, 5, 1, 3, 2))

## Example 2. Completion of partial rankings with arbitrary censoring patterns.
rankings <- rbind(c(3, NA, NA, 7, 2, NA, NA), c(NA, 6, NA, 5, NA, NA, 1),7:1)
data_completion(rankings = rankings, reference_rho = rbind(c(4, 5, 6, 1, 3, 7, 2),
                7:1, 1:7))
