Estimating tree crown model with multiple regression

Tree crown is solely responsible for the process of photosynthesis where it changes carbon dioxide to oxygen. Without these trees, our world will be full with carbon dioxide so trees are important in balancing the oxygen cycle. In this dissertation, we would like to estimate the volumetric crown...
