  • * A model was judged significant if it explained more than 14% of variance in yield or production (R2 > 0.14). This threshold was based on the 95th percentile of the R2 statistic from a Monte Carlo experiment, which computed 1000 multiple regression models for a randomly generated 42-year time series with two random predictor variables.
