crossvariogram: Subspatial CrossVariogram Calculation
In victorvicpal/MGSR: Multivariate Gaussian Subspatial Regression

Description Usage Arguments Details Value Author(s) References See Also Examples

The function calculates all possible crossvariograms within the values you referred.

1	CrossVariogram(coord,values,n=15)

`coord`	Dataframe containing the coordinates from Factorial Techniques.
`values`	Dataframe containing values from data.
`n`	Number of pairs.

Only 2 dimension allowed. Usually standarized values keep better performance. Use n_pairs_opt to evaluate it.

Object containing all possible CrossVariograms

##Data Standarization
means_vers <- apply(Versicolor,2,mean)
sd_vers <- apply(Versicolor,2,sd)
Versicolor_st <- Versicolor

for (i in 1:length(Versicolor[1,]))
{Versicolor_st[,i] <- (Versicolor[,i]-means_vers[i])/sd_vers[i]}

##PrComp
PC_train <- princomp(Versicolor_st)
## CrossVariogram Calculation
CV_vers <- crossvariogram(as.data.frame(PC_train$scores[,1:2]),as.data.frame(Versicolor_st),11)
