... stationary, they tend to produce regressions with high R-squared statistics and low DW statistics, indicating high levels of autocorrelation. This is caused by the drift in the variables often being related, but not directly accounted for in the regression, hence the omitted variable effect. ...

If the data for a case on two different variables have the same z-score, what does that mean in terms of the case in relation the population (e.g., percentile rank) and in terms of comparing the scores across the two variables (e.g., comparing SAT and ACT scores) ...

If there are m hypothesis tests and we want a procedure for which the probability of rejecting one or more hypotheses falsely (when the corresponding null hypotheses are true) to be less than a prespecified significance level α, we can accomplish this by testing each hypothesis separately and reject ...
