test.ezsim: Perform a Test for an ezsim Object

In ezsim: provide an easy to use framework to conduct simulation

Description

For each set of parameters, the simulation is ran once to obtain the value of estimator and true value to make sure everything in ezsim is properly defined. The test results will be shown in the console. The test will be ran automatically when you create an ezsim object.

Usage

## S3 method for class 'ezsim'
test(x, return_name = TRUE, print_result = FALSE, ...)

Arguments

x	An ezsim Object
return_name	Whehter to return the name of estimator
print_result	Whehter to print the return
...	unused

Value

Optional: names of estimator.
