Comparison of observed and predicted values

The model performance is compared with observed and predicted values for all cultivars across all experiments. The plots below show the observed vs predicted values for different traits. Each point represents an observation from an experiment. The closer the points are to the diagonal line, the better the performance of the model for that trait.

The range of observed and predicted values are estimated using data in this page, which may be misleading for the narrow ranges of observed and predicted values.

Using the Expand All and Collapse All buttons below, you can expand or collapse the sections for each trait to see the observed vs predicted plots for different traits.
