Balding-Nichols model

The Balding-Nichols model is a statistical description of the allele frequencies in the components of a sub-divided population. With background allele frequency p the allele frequencies in sub-populations separated by Wright's $$\scriptstyle F_\mathrm{st}\ F$$ are distributed according to independent draws from


 * $$B\left(\frac{1-F}{F}p,\frac{1-F}{F}(1-p)\right)$$

where B is the Beta distribution

The model is due to David Balding and Richard Nichols and is widely used in the forensic analysis of DNA profiles.
