Compared To Other Methods
While listwise deletion does have its problems, it is preferable to many other methods for handling missing data. In some cases, it may even be the least problematic method. The following table provides some comparisons of listwise deletions to other methods:
| Method | Comparison |
|---|---|
| Pairwise deletion | Ambiguous definition of sample size causes bias in estimated standard errors and test statistics. |
| Dummy variable adjustment | Produces biased estimates of coefficients. |

Famous quotes containing the words compared to other, compared and/or methods:
“Compared to other parents, remarried parents seem more desirous of their child’s approval, more alert to the child’s emotional state, and more sensitive in their parent-child relations. Perhaps this is the result of heightened empathy for the child’s suffering, perhaps it is a guilt reaction; in either case, it gives the child a potent weapon—the power to disrupt the new household and come between parent and the new spouse.”
—Letty Cottin Pogrebin (20th century)
“Letter-writing too often degenerates into a communicating of facts, and not of truths; of other men’s deeds and not our thoughts. What are the convulsions of a planet, compared with the emotions of the soul? or the rising of a thousand suns, if that is not enlightened by a ray?”
—Henry David Thoreau (1817–1862)
“We are lonesome animals. We spend all our life trying to be less lonesome. One of our ancient methods is to tell a story begging the listener to say—and to feel—”Yes, that’s the way it is, or at least that’s the way I feel it. You’re not as alone as you thought.””
—John Steinbeck (1902–1968)
