Quantifying sexual size dimorphism of penthetor lucasi based on cranial and dental characteristics using logistic regression analysis

Information on the sexes of specimens in the Natural History Museum is more often lacking. The prediction on sexual size dimorphism of P. /urasi was carried out using specimens from the UNIMAS FRST Museum and analyzed using an initial t-test and simple and multiple logistic regression based on thei...
