Fixed Effect Estimates for Mixed Effects Model of Memory Performance as a Function of Delay Type and Nap Status.
| Fixed Effect | ß | SE | Wald z | p |
|---|---|---|---|---|
| Intercept | 3.485 | 0.975 | 3.574 | <0.001 |
| Nap Status | −3.485 | 1.256 | −2.776 | <0.01 |
| Delay | −0.194 | 1.349 | −0.144 | 0.886 |
| Nap Status × Delay | 3.623 | 1.901 | 1.906 | 0.057 |
ß reflects estimates of the coefficients associated with the effect, SE is an estimate of the standard error of the coefficients, and Wald z represents the coefficient estimates’ distance from zero—in terms of the standard error.
