Estimating Variances and Covariances
Changing the Font
E Right-click a variable and choose Object Properties from the pop-up menu.
The Object Properties dialog box appears.
E Click the Text tab and adjust the font attributes as desired.
Establishing Covariances
If you leave the path diagram as it is, Amos Graphics will estimate the variances of the
four variables, but it will not estimate the covariances between them. In Amos
Graphics, the rule is to assume a correlation or covariance of 0 for any two variables
that are not connected by arrows. To estimate the covariances between the observed
variables, we must first connect all pairs with double-headed arrows.
E From the menus, choose Diagram > Draw Covariances.
E Click and drag to draw arrows that connect each variable to every other variable.
Your path diagram should have six double-headed arrows.
