varfreq_obs_freq: Calculate observed variant prevalence

In HopkinsIDD/phylosamp: Sample Size Calculations for Molecular and Phylogenetic Studies

Calculate observed variant prevalence

Description

This function calculates the observed variant prevalence from the coefficient of detection ratio and the actual variant prevalence. This function assumes that variant 1 is the variant of concern. This function is specific to the two-variant system.

Usage

varfreq_obs_freq(p_v1, c_ratio)

Arguments

p_v1	actual variant prevalence (proportion)
c_ratio	coefficient of detection ratio, calculated as the ratio of the coefficients of variant 1 to variant 2

Value

scalar of observed prevalence of variant 1
