↵zP value refers to the probability that the given variable for both failure types is the same.
↵yThe subscript “FP” indicates that the measurement pertains to the point of failure; the subscript “BH” indicates that the measurement refers to breast height (1.4 m [4.6 ft] aboveground).
SD = standard deviation; dbh = diameter at breast height.
