In hendriau/Summix: Summix2: A suite of methods to estimate, adjust, and leverage substructure in genetic summary data

calc_scaledObj

Description

Helper function to calculate new scaled loss function using weighted AF bin objectives

Usage

calc_scaledObj(data, reference, observed, pi.start)

Arguments

data	a dataframe of the observed and reference allele frequencies for N genetic variants. See data formatting document at https://github.com/hendriau/Summix for more information. Uses the same input data as summix.
reference	a character vector of the column names for the reference groups.
observed	a string that is the column name for the observed group.
pi.start	Length K numeric vector of the starting guess for the reference group proportions. If not specified, this defaults to 1/K where K is the number of reference groups.

Value

numeric value that is the scaled objective per 1000 SNPs
