random_scdf: Single-case data generator

Description

The random_scdf function generates random single-case data frames for monte-carlo studies and demonstration purposes. design is used to set up a design matrix with all parameters needed for the random_scdf function.

Usage

random_scdf(design = NULL, round = NA, random_names = FALSE, seed = NULL, ...)

Value

A single-case data frame. See scdf to learn about this format.

Arguments

design

A design matrix which is created by design and specifies all parameters.

round

Rounds the scores to the defined decimal. To round to the second decimal, set round = 2.

random_names

Is FALSE by default. If set random_names = TRUE cases are assigned random first names. If set "neutral", "male" or "female" only gender neutral, male, or female names are chosen. The names are drawn from the 2,000 most popular names for newborns in 2012 in the U.S. (1,000 male and 1,000 female names).

seed

A seed number for the random generator.

...

arguments that are directly passed to the design function for a more concise coding.

Examples

## Create random single-case data and inspect it
design <- design(
  n = 3, rtt = 0.75, slope = 0.1, extreme_prop = 0.1,
  missing_prop = 0.1
)
dat <- random_scdf(design, round = 1, random_names = TRUE, seed = 123)
describe(dat)

## And now have a look at poisson-distributed data
design <- design(
  n = 3, B_start = c(6, 10, 14), mt = c(12, 20, 22), start_value = 10,
  distribution = "poisson", level = -5, missing_prop = 0.1
)
dat <- random_scdf(design, seed = 1234)
pand(dat, decreasing = TRUE)
