genDataset(nC, popFreq, mu = 1000, sigma = 0.1, sorted = FALSE,
  threshT = 50, refData = NULL, mx = NULL, nrep = 1, stutt = 0,
  prC = 0, lambda = 0, beta = 1, kit = NULL)

`nC`	Number of contributors in model.
`popFreq`	A list of allele frequencies for a given population.
`mu`	Expected peak heights for a het. single contributor allele
`sigma`	Coeffecient of variance of peak heights.
`sorted`	Boolean for wheter sorting the contributors with respect to decreasingly mixture proportions.
`threshT`	Required allele peak height in mixture
`refData`	A list of given reference profiles given as refData[[i]][[s]]. Default is random from population.
`mx`	A vector of known mixture proportions. Default is random uniform.
`nrep`	Number of peak height replicates (same contributors) to generate. Default is 1.
`stutt`	A numerical stutter ratio (one ahead). Default is 0.
`prC`	A numerical dropin probability. Default is 0.
`lambda`	The rate parameter in the exponential distribution for simulating drop-in peak heights. Default is 0.
`beta`	The degradation slope parameter used for simulating degradation trend (requires valid kit to be specified). Default is 1.
`kit`	shortname of kit: "ESX17","ESI17","ESI17Fast","ESX17Fast","Y23","Identifiler","NGM","ESSPlex","ESSplexSE","NGMSElect","SGMPlus","ESX16", "Fusion","GlobalFiler"

genDataset samples random mixture peak heights given as gamma(rho*sum(h_k),tau), with h_k as peak height of k-te contributor. genData conditions on alleles given by refData. Empty references are generated with population frequencies.

List with elements theta,samples,refData where theta is the true parameters of the model. samples is a list with samples which for each samples has locus-list elements with list elements adata and hdata
