int_mat: Numerical Integration Matrix

In flexmet: Flexible Latent Trait Metrics using the Filtered Monotonic Polynomial Item Response Model

Description

Create a matrix for numerical integration.

Usage

int_mat(
  distr = dnorm,
  args = list(mean = 0, sd = 1),
  lb = -4,
  ub = 4,
  npts = 10000
)

Arguments

distr	A density function with two user-specified parameters. Defaults to the normal distribution (dnorm), but any density function is permitted.
args	Named list of arguments to distr.
lb	Lower bound of range over which to numerically integrate.
ub	Upper bound of range over which to numerically integrate.
npts	Number of integration points.

Value

Matrix of two columns. Column 1 is a sequence of x-coordinates, and column 2 is a sequence of y-coordinates from a normalized distribution.
