This study is about statistical analysis for DBH in species of major trees using in thinning out trees data. Pine forests (Eastern Forest Service) used the DBH data for six years from 2012 to 2018. And pine forests (Southern Forest Service) used the DBH data for three years from 2015 to 2018. And nut pine forests (Northern Forest Service) used the DBH data for six years from 2012 to 2018. Lastly, larch forests (Eastern Forest Service, Northern Forest Service) used the DBH data for six years from 2013 to 2019. We take growth of the DBH of each species for response variable, and degree of thinning and level of trees, age-class (of trees) for the covariates. We focus on comparing the difference of the DBH growth according to each covariates. We use ANOVA for analysis of the difference in the amount of growth in DBH, Tukey's multiple comparisons for post analysis, and regression trees for analysis of a major effect on the growth of DBH. We get some results that the effects of the thinning increase the growth of DBH and there is a difference in the growth of trees according to the level of trees and age-class.
