This function aims to find several possible distribution that would give rise to
the observed sample parameters. For that, you need to pass a list of parameters,
created with set_parameters
find_possible_distributions(
parameters,
n_distributions = 10,
seed = NULL,
return_tibble = TRUE,
return_failures = FALSE
)List of parameters, see set_parameters
The target number of distributions to return.
An integer to use as the seed for random number generation. Set this in scripts to ensure reproducibility.
Should a tibble, rather than a list, be returned? Requires the tibble-package, ignored if that package is not available.
Should distributions that failed to produce the desired SD be returned? Defaults to false
A tibble or list (depending on the return_tibble argument) with:
success or failure - character
The distribution that was found (if success) / that had the closest variance (if failure) - numeric
The exact mean of the distribution - numeric
The SD of the distribution that was found (success) / that came closest (failure) - numeric
The number of iterations required to achieve the specified SD - numeric - the first time this distribution was found
sprite_parameters <- set_parameters(mean = 2.2, sd = 1.3, n_obs = 20,
min_val = 1, max_val = 5)
find_possible_distributions(sprite_parameters, 5, seed = 1234)
