summary.sklarsomega: Print a summary of a Sklar's Omega fit.

Description

Print a summary of a Sklar's Omega fit.

Usage

# S3 method for sklarsomega
summary(object, alpha = 0.05, digits = 4, ...)

Arguments

object: an object of class sklarsomega, the result of a call to sklars.omega.
alpha: the significance level for the confidence intervals. The default is 0.05.
digits: the number of significant digits to display. The default is 4.
...: additional arguments.

Details

Unless optimization of the objective function failed, this function prints a summary of the fit. First, the value of the objective function at its maximum is displayed, along with the number of iterations required to find the maximum. Then the values of the control parameters (defaults and/or values supplied in the call) are printed. Then a table of estimates is shown. If applicable, the table includes confidence intervals. Finally, the values of AIC and BIC are displayed (if the scores are continuous and inference is parametric).

Examples

Run this code

# Fit a subset of the cartilage data, assuming a Laplace marginal distribution. Compute
# confidence intervals in the usual ML way (observed information matrix). Note that
# using confint = bootstrap leads to bootstrap sampling and bootstrap intervals.

data(cartilage)
data.cart = as.matrix(cartilage)[1:100, ]
colnames(data.cart) = c("c.1.1", "c.2.1")
