simulate_population | R Documentation |
This function allows you to create normal populations for data that would include repeated measures items. Additionally, the data can be rounded and/or truncated to ensure it matches a target scale - for example, a 1-7 type rating scale.
simulate_population(
mu = NULL,
mu_sigma = NULL,
sigma = NULL,
sigma_sigma = NULL,
number_items = NULL,
number_scores = NULL,
smallest_sigma = NULL,
min_score = NULL,
max_score = NULL,
digits = NULL
)
mu |
The population mean for the items. |
mu_sigma |
The amount of variability for each of the means (i.e., the standard deviation of the item's means) |
sigma |
The population standard deviation for each item. |
sigma_sigma |
The standard deviation of the standard deviations for the items (i.e., heterogeneity) |
number_items |
The number of items to generate |
number_scores |
The number of scores for each item to generate |
smallest_sigma |
The smallest possible standard deviation for an item that is acceptable (default is sigma_sigma/10) |
min_score |
If you want to truncate scores, what is the smallest possible score? |
max_score |
If you want to truncate scores, what is the largest possible score? |
digits |
If you want to round scores, how many digits should it be rounded to? |
The population scores with the number of items and scores specified
simulate_population(mu = 4, mu_sigma = .2, sigma = 2,
sigma_sigma = .2, number_items = 30, number_scores = 1000,
smallest_sigma = .02, min_score = 1, max_score = 7,
