Individual Change

Description

In Svensson's method, the individual change is described by the relative rank variance (RV), the observable part, and the internal rank variance (IV), the unobservable part, together. A measure of the closeness of observations to the rank transformable pattern of change is defined as the augmented correlation coefficient (ralpha) and its p-value.

Usage

rv(t)

rvse(t)

iv(t)

ralpha(t)

pralpha(t)

Arguments

t

The contingency table for Svensson's method, a two-dimension matrix.

Value

rv and iv give the RV and IV value. rvse gives the standard error of RV. ralpha and pralpha give the augmented correlation coefficient and the corresponding p-value.
