Method for printing components of an object of class MAR that provide a concise overview of the model

Usage

# S3 method for MAR
print(x,...)

Arguments

x

Object of class MAR to be printed

...

Further arguments passed to or from other methods

Details

Formats and prints the following components of a MAR object when the object's name is called: the time-series variables that were selected to be included in the model; any restrictions that were set on variable interactions; the search type used to select the best-fit model; and the coefficients, AIC values, and R^2 values of the best-fit and bootstrapped models. Other components of a MAR object can be viewed by specifying their name according to str(object).

Value

Prints a selection of components of a MAR object.

Examples

data(L4.mar)
myvar <- c(0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 0, 2)
myres <- matrix(0.5,
  nrow = length(which(myvar == 1)),
  ncol = length(which(myvar != 0))
) 
small <- L4.mar[1:20,]
run1 <- run.mar(small, variables = myvar, restrictions = myres, search = "random", boot = FALSE)
