Mark record


The Bartlett test, parallelism test and coincidence test were applied to compare four regression equations. The comparison dealt with regression equations for reduced height from total height of black spruce for four soil drainages, over till, in the High Subarctic of Quebec. It was found that form height can be extracted from total height by means of a single regression equation where soil drainage is good, moderately good or imperfect, but that a separate equation is required where drainage is poor.
