Confidence Intervals and Hypothesis Tests
Overview: Recall that a point estimator for a parameter of interest is a statistic which is a function of the random variables from which our sampling method chooses values. The properties of such an estimator, such as having a small bias or a small mean square error, are usually dependent only upon certain features of the sampling distribution of the statistic, such as its mean or variance. Ho...
متن کاملInclusion of Systematic Uncertainties in Upper Limits and Hypothesis Tests
The problem of including systematic uncertainties in upper limits on Poisson processes and in hypothesis tests is solved in a consistent and straightforward way if the uncertain quantities are treated probabilistically. This is illustrated through examples taken from the searches for new particles at ZEUS.
متن کاملBootstrap Confidence Intervals Based on Inverting Hypothesis Tests
Most confidence intervals, whether based on asymptotic theory or the bootstrap, are implicitly based on inverting a Wald test. Since Wald test statistics are not invariant under nonlinear reparametrizations of the restrictions they test, confidence intervals based on them are not invariant either. This fact explains the well-known non invariance of bootstrap confidence intervals obtained by Hal...
متن کاملConfidence Intervals and Hypothesis Testing.∗
If you have just two discrete hypotheses, then a hypothesis test is simply an application of Bayes’ Theorem. You check to see whether your data can reasonably be explained by that boring old null hypothesis (conventionally called H0), or not. To test H0, you need to compare it to one other model. One never tests a hypothesis in isolation; it is tested against an alternative (typically called H1...
متن کاملConfidence Limits and Their Robustness
Abstract Confidence limits are common place in physics analysis. Great care must be taken in their calculation and use, especially in cases of limited statistics when often one-sided limits are quoted. In order to estimate the stability of the confidence levels to addition of more data and/or change of cuts, we argue that the variance of their sampling distributions be calculated in addition to...
