Estimate skew normal alpha parameter from proportion of presymptomatic transmission

prop_presymptomatic_to_alpha(prop_presymptomatic)

Arguments

prop_presymptomatic: a numeric scalar probability (between 0 and 1 inclusive): proportion of transmission that occurs before symptom onset.

Value

A numeric scalar: The $minimum output from optimise() to find the best alpha parameter to get the desired proportion of presymptomatic transmission.
