Extreme Modelling of Missing Acacia Mangium Height Data

Abstract

Logging activity is one of the most important activities for tropical coun-
tries including Malaysia, as it produces quality trees for papers. One of the important
tree species is the Acacia Mangium which it produces a soft tree for papermaking en-
terprises. The papers are exported to Europe and countries which have high demand
for paper due to the rapid development of the printing industry. Thus we analyzed the
height for individual trees. We investigate the maximum height of the trees from 1990
to 2006 and we t the data using extreme value model. Some of the data are missing
and three imputation methods we used to solve this problem.
