Depressed Children Improve More Than Regression Can Explain

Depressed children treated with an energy drink improve significantly over a three months period. It is also the case that depressed children who spend some time standing on their head or hug a cat for 20 minutes a day will also show improvement. Incorrect causal interpretations of regression effects are not restricted to readers of the popular press. The statistician howard wayner has drawn up a long list of eminent researchers who have made the same mistake, confusing mere correlation with causation.
