A calibration curve allows to judge how well model predictions are calibrated, by comparing the predicted quantiles to the observed quantiles. Blue is the best calibrated model, see calibration (statistics). Scoring rules answer the question "how good is a predicted probability distribution compared to an observation?"
In this case, a perfect forecast results in a forecast skill metric of zero, and skill score value of 1.0. A forecast with equal skill to the reference forecast would have a skill score of 0.0, and a forecast which is less skillful than the reference forecast would have unbounded negative skill score values.

There are two main uses of the term calibration in statistics that denote special types of statistical inference problems. Calibration can mean a reverse process to regression, where instead of a future dependent variable being predicted from known explanatory variables, a known observation of the dependent variables is used to predict a corresponding explanatory variable; [1]
The combined score (right) shows that out-of-sample dominance of PW grows with training set size. With n calibration variables the total number of splits (excluding the empty set and the entire set) is 2 n −2, which becomes unmanageable. Recent research suggests that using 80% of the calibration variables for the training set is a good ...
The process approach to project management developed in the 1980s, largely in Europe. [4] The main focus of this approach is the use of structured processes throughout project execution in order to achieve its objectives. [4]
The DICE framework, or Duration, Integrity, Commitment, and Effort framework is a tool for evaluating projects, [1] predicting project outcomes, and allocating resources strategically to maximize delivery of a program or portfolio of initiatives, aiming for consistency in evaluating projects with subjective inputs.
A skill score for a given underlying score is an offset and (negatively-) scaled variant of the underlying score such that a skill score value of zero means that the score for the predictions is merely as good as that of a set of baseline or reference or default predictions, while a skill score value of one (100%) represents the best possible ...
In project management (e.g., for engineering), accurate estimates are the basis of sound project planning. Many processes have been developed to aid engineers in making accurate estimates, such as Analogy based estimation; Compartmentalization (i.e., breakdown of tasks) Cost estimate; Delphi method; Documenting estimation results; Educated ...
