The Method Of Canonical Correlation Analysis By Sampling Step By Step And Weibull Distribution Function In Prediction Model Of Diameter Construction

The method of canonical correlation analysis can overcome shortcomings in thestudy of relation between biology and environment with correlation analysis. Theprinciple and procedure of canonical correlation analysis by sampling step by step areintroduced.Using Weibull prediction model with three parameters, a, b, c and relation modelof site index, stand age with diameter class , and relation model of site index, standage, diameter class with height of diameter class, theoretical parameters of suitableconstruction distribution in Japanese larch stand, and theoretical tree number of eachdiameter class in different site index are indicated, which provides theoreticalfoundation for reasonable management of Japanese Larch.
