Table 9 Confusion matrix for all tree level microhabitat models. TP = true positive, FP = false positive, FN = false negative, TN = true negative. Specificity = TN/(TN + FP); Sensitivity = TP/(TP + FN), Accuracy = (TP + TN)/(TP + FP + TN + FN). No random effects included in predictions.

From: Assessing selected microhabitat types on living trees in Oriental beech (Fagus orientalis L.) dominated forests in Iran
