is_singular

internal

Calculates a Mahalanobis distance for every row of a set of
outcome variables (Mahalanobis, 1936
<doi:10.1007/s13171-019-00164-5>). The conditional Mahalanobis
distance is calculated using a conditional covariance matrix (i.e., a
covariance matrix of the outcome variables after controlling for a set
of predictors). Plotting the output of the cond_maha() function can
help identify which elements of a profile are unusual after
controlling for the predictors.
