Statistical Inference by Confidence Intervals: Issues of Interpretation
... rejected. That is, it is considered more plausible that the difference in outcome is due to an underlying difference between the groups than that it is due to chance factors such as variation in sampling or group assignment. The null hypothesis is rejected in favor of the alternative hypothesis. Tab ...

Since lower rates reflect a higher confidence that no losses will be incurred, this example supports the thesis that confidence has two components. In statistics, the confidence being presented is merely the general part; it does no ...

THE MODIFIED EXPONENTIAL
... The exponential distribution (ED) provides a simple, elegant and close form solution to many problems in lifetime testing and reliability studies. However, the ED does not provide a reasonable parametric fit for some practical applications where the underlying hazard rates are nonconstant, presentin ...
