indexMC: Rank the best index gages for each target site.

In wfarmer-usgs/PUBAD: Appliles and Analyzes Several Methods for Prediction in Ungaged Basins

Description

The function indexMC returns the ranking of potential index sites, by map correlation, for each target location.

Usage

indexMC(index.gages, index.obs, index.baschar, target.gages, target.obs,
  target.baschar, method = c("pearson", "kendall", "spearman"))

Arguments

index.gages	A numeric vector of the streamgage IDs to be used as potential index sites.
index.obs	A zoo object of the observed streamflows for each index gage.
index.baschar	A data frame with the LAT_GAGE_UTM, LNG_GAGE_UTM and DRAIN_SQKM for each item of index.gages.
target.gages	A numeric vector of the streamgage IDs to be used as target sites.
target.obs	A zoo object of the observed streamflows for each target gage.
target.baschar	Identical to index.baschar with respect to target.gages.
method	A character string of either "pearson", "spearman" and "kendall", specifying which correlation method to use.

Value

The function returns a list as output. This list contains:

Cor.Obs	A matrix of the observed correlation between index and target sites. The columns are in the order of target.gages and the rows are in the order of index.gages.
Cor.Netw	A matrix of the observed inter-correlation between index sites. The columns are in the order of target.gages and the rows are in the order of index.gages.
Cor.Est	A matrix of the estimated correlation between index and target sites. The columns are in the order of target.gages and the rows are in the order of index.gages.
varPar	A matrix of the variogram parameters (covariance parameters and nugget) for the variogram built on each index gage.
Rank	A matrix of the index IDs for each target gage. The columns are in the order of target.gages.
index	The input index.gages.
target	The input target.gages.
