The variance structure is chosen to improve the efficiency of the parameter estimates.
This criterion results in maximizing the differential Shannon information content of the parameter estimates.
Computer programs will often output an arbitrarily large parameter estimate with a very large standard error.
As a result, parameter estimates are biased if between study variation can not be ignored.
Ratcliff has suggested that there be at least 100 data points in the sample before the parameter estimates should be regarded as reliable.
In this case, the role of x as a moderating variable is accomplished by evaluating b, the parameter estimate for the interaction term.
The least squares parameter estimates are obtained from p normal equations.
Carla rolls the simulations for him and shows him the parameter estimates.
It has very poor convergence properties, but may be useful for finding initial parameter estimates.
These estimates involve taking ratios of statistically dependent parameter estimates.
