E o governo ainda não cria crescimento econômico...
Tema polêmico mas que não ganha muito com análises ruins, na opinião de Jude Blanchette.
O The New York Times parece ter publicado um artigo cheio de problemas. Por que? Bem, segundo Blanchette: On the first day of an introductory statistics class a student is likely to learn the maxim “correlation isn’t causation.” Simply put, the correlation (a statistical relationship) between two variables doesn’t mean that one caused the other. That the sun rises when roosters crow does not mean that roosters cause the sun to rise. To prove causation, one must employ a theory.
Economist Jeff Madrick, in his January 20 New York Times article, “Is Less Government Better for Business? Not if History Provides a Guide,” has handed a Statistics 101 class a good example of the erroneous conclusions that can be reached when correlation is confused with causation.
