On page 2, the publication reads: [Formula presented] This paragraph is missing the “[Formula presented]” and should read as described below, and the right parenthesis should be the same size as the left one in [Formula presented]. Briefly, conditioning on I, NOCIt computes: [Formula presented] where [Formula presented] is the [Formula presented]-dimensional vector of DNA mixture proportions; [Formula presented] is the [Formula presented]-simplex, which defines all possible DNA mixture proportions; [Formula presented] is the n-dimensional vector representing the change in mixture proportions for each contributor at a reference length of 200 bp from that at 0 bp owing to degradation; [Formula presented] defines all possible values for [Formula presented]; [Formula presented] is the probability density function of [Formula presented]; and [Formula presented] is the conditional probability density function of [Formula presented] given [Formula presented]. Given [Formula presented] and [Formula presented], the electropherogram for each locus [Formula presented], [Formula presented], is assumed independent of the electropherogram at every other locus.2. On page 3, the publication reads: [Formula presented] It should read as follows, in that the f0 should not be included in the equation: Lastly, we have [Formula presented] where G is the genotypes of the contributors; [Formula presented] is a [Formula presented] matrix that represents the drop-out configuration for the alleles of these contributors; and [Formula presented] is the space of all possible genotypes for n contributors.3. On page 3, the publication reads: [Formula presented] It should read as follows, in that the ‘g1’ and ‘|I′ is missing from the paragraph: If the case information I is that there is a known contributor with genotype g1, then [Formula presented] where [Formula presented] is the probability of drawing [Formula presented] random contributors with genotype [Formula presented] from the background population. To calculate the term [Formula presented], we use a probabilistic model of the electropherogram at locus l developed from calibration data of electropherograms of samples with known genotypes as described in [11].4. Some of the equations in Table 2 were incorrectly transcribed and “One KC” is meant to be centered. That is, in some instances, the “=” sign should be “|”, the symbol for “given”, while in others the “=” sign was missing from the text. The table should read as follows: 5. Some of the equations in Table 3 were incorrectly transcribed. The table should read as follows:We apologize for any inconvenience these may have caused.
