abstract:In statistics, the t-statistic is a ratio of the departure of an estimated parameter from its notional value and its standard error. It is used in hypothesis testing, for example in the Student’s t-test, in the augmented Dickey–Fuller test, and in bootstrapping.
You've seen -- I don't have the statistic in front of me, but the degree to which, say, college-educated individuals have lost their jobs in this is far greater than we've seen in other recessions.
