Statistical Analysis of Introgression
Namkoong, G. (1966). Statistical Analysis of Introgression. Biometrics, 22(3), 488-502.
Measurements of introgression may be made on scales established by principal components, canonical correlation vectors, discriminant functions, hybrid indices, and a proposed distance analysis. The distance analysis developed is the most sensitive scale used. When the methods were used on a set of data from introgression of two pine species, the failure of some of the assumptions was such as to lead to some differences in biological conclusions
