Otolith shape analysis is a widely used technique in the marine world and is often used as an indicator of the age of fish by reading the rings that appear on the otolith and is therefore considered as a tool for the differentiation of species knowing that each species of fish is characterized by a distinct form.Ī total of 180 specimens of the species Liza aurata (60 individuals of each site) were caught from Haouaria, Kélibia and and Mahdia in the coast of Tunisia. The advantage of.Tunis El Manar University, biology Department, Tunisia Effects of factors are estimated on a combination of several response variables. With the MANOVA, explanatory variables are often called factors. The main difference comes from the nature of the dependent variables: instead of a single one, we can study many of them.

Superiority trials: A superiority trial is one where you want to demonstrate that one. Three types of trials can be studied: Equivalence trials: An equivalence trial is where you want to demonstrate that a new treatment is no better or worse than an existing treatment.

Power and sample size analysis in clinical trials XLSTAT-Power enables you to compute the necessary sample size for a clinical trial. It may happen that the physico-chemical properties of a product are not sufficient to assess the quality of a product with respect to the period in which it is consumed. What is sensory shelf life analysis Sensory shelf life analysis is used to evaluate the ideal period for consumption of a product using sensory evaluation of assessors at different times/dates. The products included in the market do not have to be part of the tested products.

Once the analysis has been performed, the major advantage of conjoint analysis is its ability to perform market simulations using the obtained utilities. Principle of simulation for conjoint analysis Conjoint analysis is a comprehensive method for the analysis of new products in a competitive environment. It is especially appropriate in the case. Technically, for a given period, the cumulative incidence is the probability that an observation still included in the analysis at the beginning of this period will be affected by an event during the period. What is cumulative incidence Cumulative incidence investigates disease frequency at a certain period of time. It is often called competing risks case.
