cor–methods {MAINT.Data}

Methods for function cor in Package ‘MAINT.Data’

Description

S4 methods for function cor. These methods extract estimates of correlation matrices for the models fitted to Interval Data.

Usage

## S4 method for signature 'IdtNDE'
cor(x)
## S4 method for signature 'IdtSNDE'
cor(x)
## S4 method for signature 'IdtNandSNDE'
cor(x)
## S4 method for signature 'IdtMxNDE'
cor(x)
## S4 method for signature 'IdtMxSNDE'
cor(x)

Arguments

x

An object representing a model fitted to interval data.

Value

For the IdtNDE, IdtSNDE and IdtNandSNDE methods or IdtMxNDE, IdtMxSNDE methods with slot “Hmcdt” equal to TRUE: a matrix with the estimated correlations.
For the IdtMxNDE, and IdtMxSNDE methods with slot “Hmcdt” equal to FALSE: a three-dimensional array with a matrix with the estimated correlations for each group at each level of the third dimension.

Examples

# Create an Interval-Data object containing the intervals for 899 observations 
# on the temperatures by quarter in 60 Chinese meteorological stations.

ChinaT <- IData(ChinaTemp[1:8],VarNames=c("T1","T2","T3","T4"))

ChinaT_NE <- mle(ChinaT)

# Display correlation estimates

print(cor(ChinaT_NE))
