Selected results of the dynamic factor analysis of Normalized Difference Vegetation Index (NDVI).

aModel I: only common trends (unexplained variability), Model II: with common trends and explanatory variables (explained variability), and Model III: only explanatory variables (from multiple regression);bBIC: Bayesian Information Criterion;cCeff: Nash-Sutcliffe coefficient of efficiency. Values presented are calculated for the whole area (values in parenthesis represent range for polygons);dClassification of goodness-of-fitness results based on statistical significance (p = 0.01) for the polygon with the lowest fit in the region: −Unsatisfactory, +acceptable, ++good [85];eCanonical correlation coefficients for the first common trend of Models I and II.
