There are 2026 points in my Volker era and 5266 in my Greenspan/Bernanke era, so the correlations of -0.283 and 0.065 have z-scores of -12.7 and 4.7 respectively. These are both statistically significant from zero even at even the most stringent level like 0.1% (two-tailed), although it is arguably the difference between then that matters, which is of course even more significant since the two correlations have opposite sign.RebelEconomisthttps://www.blogger.com/profile/13241098878248190971noreply@blogger.comtag:blogger.com,1999:blog-970611666708740586.post-80539835675714260502008-07-17T11:34:00.000-07:002008-07-17T11:34:00.000-07:00Not clear that a correlation of 0.065 is statistic...Not clear that a correlation of 0.065 is statistically different from 0.Anonymousnoreply@blogger.com
