A series of statistical-dynamical models, which used regression equations based upon CLIPER output and the latest output from skill, and until the 1990s when it consistently outperformed statistical or simple dynamical models.

This longitudinal study categorized three groups of Grade 5 children into three levels of comprehenders based on a regression equation that compiled age, word reading accuracy, word reading speed, and nonverbal cognitive ability.

Specification of the regression equation is very straightforward : one includes as explanators ( right-hand side variables in the regression ) the one-period-lagged value of the dependent variable and the current value of the independent variable:

A point that has a greater Mahalanobis distance from the rest of the sample population of points is said to have higher leverage since it has a greater influence on the slope or coefficients of the regression equation.

A review examined whether hold tests, best estimate or regression equation methods were most accurate in predicting overall IQ ( full scale IQ ) as determined by Wechsler Adult Intelligence Scale ( WAIS-R ) in a non-neurologically impaired population.

Sample size requirements to achieve a particular significance and power in SEM hypothesis testing are similar for the same model when any of the three algorithms ( PLS-PA, LISREL or systems of regression equations ) are used for testing.
37.
One specific example of this arose when developing a regression equation based on a clinical trial, in which blood pressure was the average of six measurements, for use in clinical practice, where blood pressure is usually a single measurement.

If a linear relationship between the " x " and " y " variates exists and the regression equation passes through the origin then the estimated variance of the regression equation is always less than that of the ratio estimator.

By retaining E, P, and Z as separate variables, results from polynomial regression equations can be translated into three-dimensional surfaces, whose properties can be formally tested using procedures set forth by Edwards and Parry ( 1993; see also Edwards, 2002 ).
