getPHIrexpec: Mathematical expectancy of the PHIr statistic -PHIrexpec-

In DLEIVA/DyaDA: Dyadic Data Analysis

Description

Function to obtain mathematical expectancy of the PHIr statistic under a specified null hypothesis regarding social reciprocity and by means of the observed sociomatrix.

Usage

   getPHIrexpec(X,pi)

Arguments

X	Original sociomatrix.
pi	Matrix of probabilities Pij that specifies the null hypothesis regarding social reciprocity.

Details

getPHIrexpec computes the mathematical expectancy of the PHIr statistic under any null hypothesis. The null hypothesis of complete reciprocation could be of interest to social researchers. This hypothesis can be represented as Pij = .5 for all i and j.

Value

PHIrexpec

Mathematical expectancy of the PHIr statistic under the specified null hypothesis.
