Summary of structure parameters

structure parameters
K: number of clusters
N: number of individuals
L: number of loci
qij: admixture proportion of individual i in cluster j
zilm: cluster of origin for locus l, individual i, copy m
(α1, … , αK): parameters to Dirichlet distribution which forms a prior for qi
pklj: frequency of allele j in locus l, cluster k
λ: parameter to Dirichlet distribution which forms a prior for pkl.
Fk: the amount of drift from ancestral population to cluster k in the model of correlated allele frequencies
New model parameters
S: number of sampling locations
r: parameter which estimates the informativeness of the sampling location data
(η1, … , ηK): for the no-admixture model, these parameters reflect the relative proportion of individuals assigned to each cluster
(γs1, … , γsK): for the no-admixture model, these parameters reflect the relative proportion of individuals from location s assigned to each cluster
(${\alpha }_1^{(g)}$, …, ${\alpha }_{\mathrm{K}}^{(g)}$): for the admixture model, these parameters reflect the relative levels of admixture from each cluster over all individuals
(αs1, … , αsK): for the admixture model, these parameters reflect the relative levels of admixture from each cluster for an individual from location s
