Confidence intervals for the Mann–Whitney test

Statistical Methods in Medical Research, 2018
The Mann–Whitney test is a commonly used non-parametric alternative of the two-sample t-test. Despite its frequent use, it is only rarely accompanied with confidence intervals of an effect size.

Understanding confidence intervals

BMJ, 2014
Researchers investigated the effects of controlled cord traction in the third stage of labour on postpartum haemorrhage when carried out in a high resource setting. A randomised controlled trial study design was used. Control treatment was standard placenta expulsion (awaiting spontaneous placental separation before facilitating expulsion). The setting

Confidence Intervals II

1998
In the previous topic you began a study of the important and widely used technique of confidence intervals. These procedures use a sample statistic to estimate a population parameter with an interval of values and a certain confidence level. This topic asks you to continue this study by considering sample survey results and the connection between ...

Distribution‐free confidence intervals

Statistica Neerlandica, 1972
Summary  A general approach for converting a certain class of nonparametric tests into confidence intervals for suitably defined parameters is discussed. The class of tests comprises but is not limited to lineair rank tests for the one‐sample, two‐sample, and linear regression problems.

Confidence intervals and hypothesis testing for high-dimensional regression

Journal of machine learning research, 2013
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.
