Statistical models related to accumulated biomass of Hopea odorata in three soil series of ultisols

This paper presents results on statistical distribution fitting and polynomial regression on accumulated biomass of seven year-old tree species Hopea odorata, which were planted in three different soil series of ultisols, namely Rengggam, Baling and Kuala Berang. Data were collected from a study con...
