compute_resolution: Compute resolution of forecasts, normalised by the uncertainty
Description
The resolution is computed as the mean squared distance to a base rate (reference forecast) and
is then normalised by the uncertainty (maximum resolution).
This means the output is between 0 and 1, 1 corresponding to the maximum resolution.
Usage
compute_resolution(f, p0)
Arguments
f
Vector of forecasts
p0
Vector of base rate.
In the case rate is usually the prevalence of a uniform forecast (e.g. 1 / number of categories)
but can depend on the observation (hence the vector).
