extract_estimates: Extract estimates for a given factor combination

In HDANOVA: High-Dimensional Analysis of Variance

Extract estimates for a given factor combination

Description

Extracts and sums the LS estimates for a given factor combination from an object of class hdanova. If add_residuals is TRUE, the residuals are added to the LS estimates. If substract is TRUE, the returned matrix is the data with chosen estimates subtracted.

Usage

extract_estimates(object, factors, subtract = FALSE, add_residuals = FALSE)

Arguments

object	asca object.
factors	vector of factor names or numbers.
subtract	logical subtract the estimates from the data (default = FALSE).
add_residuals	logical add residuals to the estimates (default = FALSE).

Value

A matrix of the extracted estimates.

Examples

# Load candies data
data(candies)

# Basic HDANOVA model with two factors and interaction
mod <- hdanova(assessment ~ candy * assessor, data=candies)

# Extract estimates for the interaction
inter <- extract_estimates(mod, c("assessor:candy"))

# Visualize the interaction effect
image(t(inter), main="Interaction effect", xlab="Attribute", ylab="Sample")
