Notes: P-values are for two-tailed hypothesis tests that a parameter is equal to zero vs. that it is not. A P-value is not provided for the Intercept of the growth model because we did not hypothesize that this value would differ from zero given that Functional Limitations cannot take on the value of 0. The Quadratic Growth model includes a first-order autoregressive covariance structure for the occasion-specific residuals.
