Determinação do número de ínstares de insetos utilizando modelo de regressão segmentado
Data from populations of Anticarsia gemmatalis Hübner larvae, and simulated data considering fixed and variable proportions of larvae head capsules sizes of successive instars, were fit into a segmented polynomial regression. The joint points corresponded to the change of instars and the larvae growing process was represented by a sequence of submodels. This allowed the accurate estimation of the mean size of larvae head capsule, and the confidence interval for each instar.
