RaschSampler (version 0.8.0)

rsctrl: Controls for the Sampling Function

Description

Various parameters that control aspects of the random generation of binary matrices.

Usage

rsctrl(burn_in = 100, n_eff = 100, step = 16, seed = 0, tfixed = FALSE)

Arguments

burn_in

the number of sampled matrices to come close to a stationary distribution. The default is burn_in = 100. (The actual number is 2 * burn_in * step.)

n_eff

the number of effective matrices, i.e., the number of matrices to be generated by the sampling function rsampler. n_eff must be positive and not larger than 8191 (2

step

controls the number number of void matrices generated in the the burn in process and when effective matrices are generated (see note below). The default is step = 16.

seed

is the indicator for the seed of the random number generator. Its value must be in the range 0 and 2147483646 (2**31-2). If the value of seed equals zero, a seed is generated by the sampling function

tfixed

logical, -- specifies if in case of a quadratic input matrix the diagonal is considered fixed (see note below). The default is tfixed = FALSE.

Value

• A list of class RSctr with components burn_in, n_eff, step, seed, tfixed.,
