Confidence Intervals and Hypothesis Testing for High-Dimensional Statistical Models

Fitting high-dimensional statistical models often requires the use of non-linear parameter estimation procedures. As a consequence, it is generally impossible to obtain an exact characterization of the probability distribution of the parameter estimates. This in turn implies that it is extremely challenging to quantify the uncertainty associated with a certain parameter estimate. Concretely, no...

Generalized Confidence Intervals and Fiducial Intervals for Some Epidemiological Measures

For binary outcome data from epidemiological studies, this article investigates the interval estimation of several measures of interest in the absence or presence of categorical covariates. When covariates are present, the logistic regression model as well as the log-binomial model are investigated. The measures considered include the common odds ratio (OR) from several studies, the number need...

Testing statistical hypotheses based on fuzzy confidence intervals

Abstract: A fuzzy test for testing statistical hypotheses about an imprecise parameter is proposed for the case when the available data are also imprecise. The proposed method is based on the relationship between the acceptance region of statistical tests at level β and confidence intervals for the parameter of interest at confidence level 1 − β. First, a fuzzy confidence interval is constructe...

Confidence 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...

Significance Testing and Confidence Intervals

probabilities, it can be determined that combining the probability values of 0.11 and 0.07 results in a probability value of 0.045. Therefore, these two nonsignificant findings taken together result in a significant finding. Although there is never a statistical basis for concluding that an effect is exactly zero, a statistical analysis can demonstrate that an effect is most likely small. This ...
