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

Calculate probability of detecting a variant assuming cross-sectional sampling

Description

This function calculates the probability of detecting the presence of a variant given a sample size and assuming a single, cross-sectional sample of detected infections.

Usage

vartrack_prob_detect_xsect(p_v1, n, omega, c_ratio = 1)

Arguments

p_v1	variant prevalence (proportion)
n	sample size
omega	probability of sequencing (or other characterization) success
c_ratio	coefficient of detection ratio, calculated as the ratio of the coefficients of variant 1 to variant 2. Default = 1 (no bias)

Value

scalar of expected sample size
