calcQual(evids, knownContr, knownNonContr, nUnknowns, theta, prD, prC, freq)
evids |
vector of alleles present at a given locus for any number of replicates. Same as 'Repliste' in likEvid function. |
knownContr |
vector of genotypes for the known contributors. Genotype 12/17 should be given as a vector c(12,17) and genotypes 12/17,14/16, should be given as a unique vector: c(12,17,14,16). If empty, set to 0. |
knownNonContr |
vector of genotypes for the known non-contributors |
nUnknowns |
Number of unknown individuals under H. Set to 0 if there are no unknown contributors. |
theta |
theta correction, value must be taken in [0,1) |
prD |
probability of heterozygotes dropout. It is possible to assign different values per contributor. |
prC |
probability of drop-in applied per locus |
freq |
vector of the corresponding allele frequencies of the analysed locus in the target population |
Assumes that prD is a identical for all contributors. Otherwise running forensim::likEvid (or possibly other implementations) From likEvid documentation: If there are two replicates, showing alleles 12,13, and 14 respectively, then evids should be given as c(12,13,0,14), where the 0 is used as a separator. An empty replicate is simply 0. For example, replicates (12,13) and and one empty replicate must be given as: c(12,14,0,0).
