lrMix

Calculates the likelihood ratio for pairs of profiles under the propositions
\(H_p:\qquad V+S\) and \(H_d:\qquad \)\( V+U\), where \(V\), \(S\) and \(U\) are the victim, the
suspect and someone unrelated to the suspect respectively. The calculation
does not employ \(\theta\) so there are no assumptions about the
subpopulations of the contributors.

A set of tools to explore the behaviour statistics used for forensic DNA interpretation when close relatives are involved. The package also offers some useful tools for exploring other forensic DNA situations.

lrMix function

<dl><dt>profiles</dt>
<dd>A vector of profile lists, from <code>randomProfilePairs</code>.
<code>randomPCPairs</code> and <code>randomSibPairs</code> also work but should not
really be used as the calculations do not take account of the relationship
between the two individuals.</dd>
<dt>Freqs</dt>
<dd>A list containing elements <code>freqs</code>, <code>loci</code> and
<code>counts</code>. The element <code>freqs</code> is a list of vectors of allele
frequencies at the loci listed in <code>loci</code>. These frequencies are used to
evaluate the LR</dd></dl>
