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

Calculate sample size needed for variant detection assuming cross-sectional sampling

Description

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

Usage

vartrack_samplesize_detect_xsect(p_v1, prob, omega, c_ratio = 1)

Arguments

p_v1	variant prevalence (proportion)
prob	desired probability of detection
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
