getShapes {DNAmixturesLite}

Shape parameters for a mixture with known contributors only

Description

The function is mainly for internal use. It calculates the shape parameters, or contribution to the shape parameter, that correspond to the known contributors in the mixture.

IMPORTANT: This is the DNAmixturesLite package, which is intended as a service to enable users to try DNAmixtures without purchasing a commercial licence for Hugin. When at all possible, we strongly recommend the use of DNAmixtures rather than this lite-version. See https://dnamixtures.r-forge.r-project.org/ for details on both packages.

While the lite-version seeks to provide the full functionality of DNAmixtures, note that computations are much less efficient and that there are some differences in available functionality. Be aware that the present documentation is copied from DNAmixtures and thus may not accurately describe the implementation of this lite-version.

Usage

getShapes(mixture, pars, allelecounts = NULL)

Arguments

mixture

A DNAmixture.

pars

Model parameters.

allelecounts

This argument is possibly redundant.

Value

For each marker a matrix of shape-parameters.

mix <- DNAmixture(list(MC15, MC18), C = list(50,50), k = 3, K = c("K1", "K3", "K2"),
database = USCaucasian)
p <- mixpar(rho = list(30, 30), eta = list(30, 30), xi = list(0.08,0.08),
            phi = list(c(K2 = 0.1, K3 = 0.2, K1 = 0.7), c(K2 = 0.1, K3 = 0.2, K1 = 0.7)))
