@article{burrows_1975, title={VARIANCES OF SELECTION DIFFERENTIALS IN NORMAL SAMPLES}, volume={31}, ISSN={["0006-341X"]}, DOI={10.2307/2529714}, abstractNote={Standardized variances of selection differentials are defined in general and then considered in detail for the case of directional selection on the basis of normally distributed test scores. Symmetry properties, bounds and asymptotic values for the variances are derived. The results are used to investigate the variance of response to selection.}, number={1}, journal={BIOMETRICS}, author={BURROWS, PM}, year={1975}, pages={125–133} }
 @article{burrows_cockerham_1974, title={DISTRIBUTIONS OF TIME TO FIXATION OF NEUTRAL GENES}, volume={5}, ISSN={["1096-0325"]}, DOI={10.1016/0040-5809(74)90041-0}, abstractNote={Exact distributions of times to fixation are derived for neutral alleles in a discrete generation, constant census model that accommodates specified variations in gametic contributions per parent. This enables an evaluation of the performance of the effective number concept, and of diffusion equation approximations, used to characterize the time scale of drift events. Following simultaneous comparisons of modes, medians, means and standard deviations of exact and approximate distributions of times to fixation, it is concluded that diffusion equation methods, in conjunction with the appropriate effective number, do produce accurate results.}, number={2}, journal={THEORETICAL POPULATION BIOLOGY}, author={BURROWS, PM and COCKERHAM, CC}, year={1974}, pages={192–207} }
