Changes in plot random effect from past models

Compare plot random effect with last model to check how variance is changing.

Mortality in function of fixed effects

Accuracy

Using four different metrics:

  • Sensitivity measures the percentage of dead trees that are identified as dead
  • Specificity measures the percentage of alive trees that are correctly identified as alive
  • Accuracy is the ratio of number of correct predictions to the total of predictions
  • Accuracy balanced considers unbalanced accuracy predictions of positive and negative events (sensitivity and specificity)
