Good day,
I am part of a frog monitoring project where we are using the robust design to answer questions about survival between diseased and non-diseased individuals. We go four times in the active season (spring-fall), and each primary sessions consist of three nights (secondary sessions). I would like to know if the study design could be improved by increasing the number of primary sessions and reducing the number of secondary sessions to just two nights instead of three. Is there a way to determine how many secondary sessions one should perform within a primary session? Is this related to getting sufficient recaptures?
Kind regards,
Matt
