Chi-square statistic of the test of bivariate normality.
The column thresholds.
Its degrees of freedom, r c − r − c.
The number of observations (the total of the table).
The correlation (NaN where polycor returns NA).
The row thresholds (the estimates with ML, the two-step ones otherwise).
Variances and covariances of the estimates (the inverse of the negative Hessian of the log-likelihood at the
maximum), in the order rho, the row thresholds, the column thresholds; 1 × 1 (rho alone) without ML.
polycor's warnings, in order.
Result of polychor with
stdErr.
