Mardia's Test for Multivariate Normality
Description
Performs Mardia’s skewness and kurtosis tests to assess multivariate normality in a multivariate dataset.
Usage
mardia(
data,
use_population = TRUE,
tol = 1e-25,
bootstrap = FALSE,
B = 1000,
cores = 1
)
Arguments
data |
A numeric matrix or data frame with observations in rows and variables in columns. |
use_population |
Logical; if |
tol |
Numeric tolerance passed to |
bootstrap |
Logical; if |
B |
Integer; number of bootstrap replicates. Only used when
|
cores |
Integer; number of cores to use when |
Value
A data frame with two rows, one for Mardia's skewness test and one for the kurtosis test.
Each row contains the name of the test (Test
), the test statistic (Statistic
),
and the associated p-value (p.value
).
