We give expansions for unbiased estimators based on the arithmetic mean of an analytic function of the non-centrality parameter of the non-central chi-square distribution. The terms of these expansions depend on the derivatives of the function to be estimated and on certain polynomials which are con
## Abstract We present a new method, the Ξ΄βcentralization (DC) method, to correct for population stratification (PS) in caseβcontrol association studies. DC works well even when there is a lot of confounding due to PS. The latter causes overdispersion in the usual chiβsquare statistics which then h
