PAMfmado | R Documentation |
Performs clustering of time series of maxima using the pam
algorithm
tailored for the F-madogram distance.
PAMfmado(x, K, J = 0, threshold = 0.99, max.min = 0)
x |
A matrix of maxima. For example, for weekly maxima of precipitation,
the number of stations is |
K |
Number of clusters. |
J |
Number of resamplings for which the stations are randomly moved to break
the dependence. By default, |
threshold |
Quantile level used for the resampling threshold.
The corresponding quantile is printed (when |
max.min |
A lower threshold to remove very small values.
For example, some rain gauges cannot go below 2 mm. Default is |
An object of class "pam"
representing the clustering.
See pam.object
for details.
