Parameters ¶ Location Parameter ¶ For the location parameter, recall the formulation
μ ( s , θ ) = μ 0 \boldsymbol{\mu}(\mathbf{s},\boldsymbol{\theta}) =
\mu_0 μ ( s , θ ) = μ 0 So for this experiment, each model has a location bias parameter, μ 0 \mu_0 μ 0 .
However, the temporal model includes the location-bias parameter and the location-temporal weight parameter, μ 1 \mu_1 μ 1 .
In addition, the spatial model includes all parameters in the above equation.
Location-Bias ¶ Histogram ¶ This is the histogram of all samples of the location-bias parameter, μ 0 \mu_0 μ 0 , for each station in Spain.

Scale ¶ Recall, the parameterization for the scale parameter is given by
σ ( t ; θ ) = σ 0 \sigma(t;\boldsymbol{\theta})
=
\sigma_0 σ ( t ; θ ) = σ 0 where σ 0 \sigma_0 σ 0 is the scale parameter per station.
This means that each model will have the same scale parameterization.

Concentration ¶ Recall, the parameterization for the shape parameter is given by
κ ( t ; θ ) = κ 0 \kappa(t;\boldsymbol{\theta})
=
\kappa_0 κ ( t ; θ ) = κ 0 where κ 0 \kappa_0 κ 0 is the shape parameter per station.
This means that each model will have the same shape parameterization.

Rate ¶ We can relate the GEVD parameters to the GPD .
This gives us a rate parameter, λ, which is the expected number of events that exceed some threshold, y 0 y_0 y 0 , per year.
λ = σ + κ ( y 0 − μ ) \lambda = \sigma + \kappa (y_0 - \mu) λ = σ + κ ( y 0 − μ ) However, we need to define an exceedence threshold, y 0 y_0 y 0 .
We will do a simple 95% quantile for each independent station with a declustering of 3 days.
Then we can calculate the rate, λ.
