Creates a list of summary statistics to pass to mimic.
set_stats(d = 2, means = 0, variances = 1, correlation = diag(2))An integer that is no smaller than 2.
A numeric vector of sample means.
A numeric vector of positive sample variances.
A numeric correlation matrix. None of the off-diagonal
entries in correlation are allowed to be equal to 1 in absolute value.
A list containing the following components.
means a d-vector of sample means.
variances a d-vector sample variances.
correlation a d by d correlation matrix.
The vectors means and variances are recycled using
rep_len to have length d.
