=== Estimation of free model coefficients ===

Model coefficients fixed at zero0.0, 1.0, or other values, do not require estimation because they already have specified values. Estimated values for free model coefficients are obtained by maximizing fit to, or minimizing difference from, the data relative to what the data's features would be if the free model coefficients took on the estimated values. The model's implications for what the data should look like for a specific set of coefficient values depends on:

a) the coefficients' locations in the model (e.g. which variables are connected/disconnected),

b) the nature of the connections between the variables (covariances or effects; with effects often assumed to be linear),
