A note on studentized confidence intervals for the change-point

Marie Hušková, Claudia Kirch
2009 Computational statistics (Zeitschrift)  
Since the asymptotic distribution of change-point statistics for time-series depends on this value, having a good estimator under the null as well as alternatives is essential for testing problems.  ...  A simulation study shows that we obtain better intervals by studentizing. When studentizing dependent data, we need to use flat-top kernels for the estimation of the asymptotic variance.  ...  Acknowledgement The authors would like to thank D. Politis (University of California, San Diego) for bringing the relevant papers to our attention.  ...

Variation of the fine-structure constant: an update of statistical analyses with recent data

L. Kraiselburd, S. J. Landau, C. Simeone
2013 Astronomy and Astrophysics  
We tested the consistency using the Student test and confidence intervals. We splited the data sets in to smaller intervals and grouped them acording to redshift and angular position.  ...  Results show consistency for the reduced intervals for each pair of data sets and suggests that the variation in \alpha is significant at higher redshifts.  ...  Support for this work was provided by PIP 0152/10 CONICET. The authors are grateful to Raghunathan Srianand for providing enlarged errors of the VLT data.  ...

2017 Journal of the Operational Research Society  
The confidence intervals from bootstrapping allow part of the uncertainty of point estimates stemming from sample variation to be revealed.  ...  However, when comparing with growth in labour input the impact on productivity vary a lot.  ...  A few quite small units have rather wide confidence intervals for all the panels.  ...

The Regression Smoother LOWESS: A Confidence Band That Allows Heteroscedasticity And Has Some Specified Simultaneous Probability Coverage

Rand Wilcox
2017 Journal of Modern Applied Statistical Methods  
A trivial way of computing a confidence band is to compute confidence intervals for K covariate values, each having probability coverage 1 − α.  ...  When using the LOWESS estimator, an extant method that assumes homoscedasticity can be used to compute a confidence interval for M(Y|X = x).  ...  The method for adjusting the confidence intervals has certain similarities to using a Studentized maximum modulus distribution, but it differs in ways that will be fairly evident.  ...
