Statistical Evaluation of a Multiple Response Experiment: Alterations to the Morphology of Rat Molars

Abstract

SYNOPSIS IN INTERLINGUA

EVALUTATION STATISTIC DE UN EXPERIMENTO A RESPONSA MULTIPLE; ALTERATIONES AL MORPHOLOGIA DE MOLARES DE RATTO.-Quando il existe multe mesuramentos pro cata unitate experimental, il es multo plus efficace determinar le variantia per methodos de analyse a multiple variabiles que per separate analyses a un sol variabile. In le presente studio, separate analyses a un sol variabile monstrava que le administration de fluoruro alterava 6 de 8 characteristicas de molares del ratto. Methodos a multiple variabiles confirmava ille conclusion, sed illos etiam monstrava que le plus grande parte del effecto general poteva esser explicate per alterationes in non plus que 2 del characteristicas. Le altere characteristicas non experien- tiava alterationes independente. Fluoruro in le presentia de molybdenum e molybdenum sin fluoruro produceva differente resultatos.
