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