iro: Item Response Ratio

In sdap: Statistical Data Preparation Indicators

Description

The item response ratio measures the impact of the missingness on the total of a variable in the final dataset (or in data sets where already a number of values have been imputed).

Usage

iro(data, r1ij, bij, obsi = 1:nrow(data), varj = 1:ncol(bij), weight)

Arguments

data	(mandatory): A dataframe containing the data to be processed.
r1ij	(mandatory): A matrix containing the response indicators of dataset 1.
bij	(optional): A matrix containing the structurally missingness indicators. bij can be calculated using the function smind. If the argument bij is missing, the indicator irr is calculated without considering a misingness indicators matrix.
obsi	(optional): A vector with the observations in rij to to be processed. If the argument obs is missing, all observations are processed.
varj	(optional): A vector with the variables (column numbers) to be considered for the calculation. If the argument varj is missing, all variables are considered for the indicator.
weight	(optional): A vector of weights to be considered when calculating the indicator. If no weight vector is given as an argument, the indicator is calculated without considering different weights.

Value

A list with the following elements: variables (variables), observations (observations), Indicator IMR (imr).
