match_kde_height: Estimate variance by comparison to a density estimate

In lculibrk/Ploidetect: Ploidetect - Detection of tumour purity, aneuploidy, and copy number variation from whole genome sequnce data

Estimate variance by comparison to a density estimate

Description

match_kde_height returns standard deviation such that the probability density function of the gaussian mixture model (GMM) specified by the "means" parameter closely matches the kernel density estimation for the input data

Usage

match_kde_height(data, means, sd, comparison_point = NA)

Arguments

data	input data to estimate density and mix the mixture model to
means	the means of the GMM
sd	the initial estimate of standard deviation
comparison_point	value to compute density function and density estimator height for optimization

Value

an estimation of standard deviation
