Math · Statistics and Probability · Statistics and Probability questions and answersThe test statistic of z is obtained when testing the claim that p. This is a two-tailed test. Using a significance level, complete parts (a) and (b). Find the critical value(s). should we rejecto H0 or should we fail to reject H0?

F Statistic / F Value: Simple Definition and Interpretation

If you don’t have statistically significant results, you throw your test data out (as it doesn’t show anything!); in other words, you can’t reject the null hypothesis. You can use the F statistic when deciding to support or reject the null hypothesis. In your F test results, you’ll have both an F value and an F critical value. In general, if your calculated F value in a test is larger than your F critical value, you can rej ...

time series - Why does the ADF test have a higher critical value than its t-stat

I did a ADF test to my data set to find unit root using STATA. I get t-test test statistic which is -2.363 from ADF. I think it is much lower than -1.96 so it can reject the null. But actually its
