Summary
An algorithm for estimating mean stage durations, the standard deviations associated with the means, and stage-specific survivorships from stage frequency data is presented. The algorithm is based on an age-structured, distributed delay simulation model which usesErlang distributions to determine the probability of maturity for individuals in each stage. If the data set extends beyond the first generation, the algorithm requires a fecundity rate, as well as stage frequencies, as input. Goodness-of-fit was measured using a weighted least squares calculation summed over all observed stages and all sampling dates.
