1. :It sounds like you want Sequential probability ratio test ( SPRT ). 2. Extensions to ratio test , however, sometimes allows one to deal with this case. 3. Does the ratio test only work for series and not sequences? 4. Comparison functions are necessarily entire, which follows from the ratio test . 5. That is quite different from doing any sort of ratio test . 6. The models being compared need not be F-test or a likelihood ratio test . 7. If the ratio test is inconclusive, and the series may converge or diverge. 8. A general approach in a frequentist analysis can be based on maximum likelihood-ratio tests . 9. With sequences, the ratio test only determines convergence to zero. 10. One such statistic is the chi-square likelihood-ratio test , which assesses the difference between models.
