Calculate cross site variation

Description

Given a set of impact estimates and associated standard errors, use method of moments to calculate the implied cross site variation, assuming the standard errors are correct (and that site-specific impacts are independent of precision).

Usage

calc_cross_site_variation(Y, SE)

Arguments

Y

List of estimated impacts for sites

SE

List of standard errors for the estimated impacts.

Details

For discussion of this approach, see pg 241 of Handbook of Quantitative Methods for Educational Research, Timothy Teo (Ed.)

Value

Grand mean, Q statistic, and estimated tau (cross site variation).
