Description

Calculates the adjusted weight for a given main-item of a linguistic questionnaire

Usage

adjusted.weight.MI(x, i, j, b_j, b_jk, SI)

Arguments

x	the data set to evaluate.
i	an observation index.
j	a main-item index.
b_j	an array referring to the initial weights given to each main-item of the considered main-item. This array will be afterwards re-calculated.
b_jk	a matrix of length(b_j) rows and max(SI) columns expressing the initial weights of each sub-item of a given main-item.
SI	an array representing the total numbers of sub-items per main-item.

Value

A numerical value giving the readjusted weight of the main-item j for the observation i.
