Bi-factor model for the cognitive <i>baseline</i> data.
<p>Eighteen variables from nine tests were used to estimate the model with a global cognitive factor capturing covariation across all variables and four <i>independent</i> secondary factors explaining specific shared covariations <i>beyond</i> that shared with other variables.</p
