.fcst |
A |
parameter |
The name of the column for the observed data. |
thresholds |
A numeric vector of thresholds for which to compute the Brier Score. |
groupings |
The groups for which to compute the ensemble mean and spread. See group_by for more information of how grouping works. |
climatology |
The climatology to use for the Brier Skill Score. Can be "sample" for the sample climatology (the default), a named list with elements eps_model and member to use a member of an eps model in the harp_fcst object for the climatology, or a data frame with columns for threshold and climatology and also optionally leadtime. |
rel_probs |
Probabilities to use for reliability diagrams. Set to NA (the default) to select automatically. |
num_ref_members |
The number of members for which to compute the fair Brier score. |
keep_score |
|
... |
Used internally depending on the class of the input. |
A data frame with data grouped for the groupings column(s) and
columns for brier_score, brier_skill_score and the
deomposition of the brier score - brier_score_reliability,
brier_score_resolution and brier_score_uncertainty.
