In victorvicpal/MGSR: Multivariate Gaussian Subspatial Regression

Description

Help Function to choose the proper number of pairs for the crossvariogram.

Usage

n_pairs_opt(coord, values, n_min = 12, n_max = 20)

Arguments

coord	Dataframe containing the coordinates from Factorial Techniques.
values	Dataframe containing values from data.
n_min	minimal number of pairs to be checked
n_max	maximal number of pairs to be checked

Details

Plotting

Value

Object containing all (max - min) values of pairs and the suggested one.

Examples

data("iris")
Versicolor <- iris[which(iris$Species=='versicolor'),-5]
##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
n_pairs <- n_pairs_opt(as.data.frame(PC_train$scores[,1:2]),as.data.frame(Versicolor_st),6,15)
plot(n_pairs$dif_pairs)
