matpesos {climatol} | R Documentation |
Computation of the inter-station weight matrix that will be used by
datest
to estimate each station series from all other stations.
matpesos(wa=5, wz=.001, verb=TRUE)
wa |
Shape parameter of the weighting function 1/(1+d^2/wa) ,
where d stands for distance. Low values (1-10) increase the weight of
nearby stations, while high values (>1000) take in account also the
far stations influence. Do wa=0 if you want an unweighted average of
all the stations. |
wz |
Scale parameter of the vertical coordinate Z . The default
value assumes that X and Y are expressed in km, while
Z is expressed in m. Can be used to change the Z weight in
inter-station distance computations. |
verb |
If TRUE , progress indications will be shown in the
terminal. |
Object est.w
is created, containing the computed weight matrix.
