Setting of the error and patient population: errors in certain specialty or ancillary care settings, such as radiology, appear to be less common than errors in clinical medicine.
Thus, for a comparison with other larger studies, our investigation lacked an age-matched control group, which made it difficult to control for population errors.
Variance components for populations, families within populations, and error were determined for each trait at each site and in each year using PROC MIXED.
We determined continuous T-scores (standardized to a nonclinical population) for errors of commission, errors of omission, and hit reaction time (Conners and Staff 2001).
A correct general linear model operates under general assumptions concerning the population of error values ε (residuals).
Those propounding despicable racial slurs against the duly elected President of the United States are, presumably, a population rounding error and a lamentable, lunatic fringe -- but in the Twitterverse, they are regrettably audible just the same.
In a simple regression model of a behavioural relationship using ordinary least squares applied to a random sample from a larger population, the error terms are assumed to be randomly distributed with an expected value of zero.
