ATA: Run Automated Test Assembly

Description

Perform Automated Test Assembly with specified configurations.

Usage

ATA(config, constraints, plot = FALSE, plot_range = c(-3, 3))
# S4 method for config_ATA
ATA(config, constraints, plot = FALSE,
  plot_range = c(-3, 3))

Arguments

config

An '>config_ATA object containing configuration options. Use createStaticTestConfig for this.

constraints

A list representing optimization constraints. Use loadConstraints for this.

plot

Logical. If TRUE, draw Fisher information plot from the selected items.

plot_range

Numeric. A vector of length 2 containing the lower and upper bounds of plot range. The default is c(-3, 3).

Value

A list containing the following entries:

• MIP A list containing the result from MIP solver.

  • solution Solution vector. Each value represents an item. A value of 1 indicates the item was selected.

  • objval Objective value of the solution.

  • status Status value indicating whether an optimal solution was found.

• selected The attributes of the selected items.

• solver The name of the MIP solver used in the assembly.

• obj_value Objective value of the solution. Identical to the one above.

• solve_time The elapsed time in running the solver.
