Common pitfalls in statistical analysis: Clinical versus statistical significance

open access: yesPerspectives in Clinical Research, 2015
In clinical research, study results, which are statistically significant are often interpreted as being clinically important. While statistical significance indicates the reliability of the study results, clinical significance reflects its impact on ...

Variable-width confidence intervals in Gaussian regression and penalized maximum likelihood estimators [PDF]

open access: yesarXiv, 2010
Hard thresholding, LASSO , adaptive LASSO and SCAD point estimators have been suggested for use in the linear regression context when most of the components of the regression parameter vector are believed to be zero, a sparsity type of assumption. Potscher and Schneider, 2010, Electronic Journal of Statistics, have considered the properties of fixed ...

Confidence intervals in within-subject designs: A simpler solution to Loftus and Masson's method

open access: yes, 2005
Within-subject ANOVAs are a powerful tool to analyze data because the variance associated to differences between the participants is removed from the analysis.

Simple Confidence Intervals for MCMC Without CLTs [PDF]

open access: yesarXiv, 2018
This short note argues that 95% confidence intervals for MCMC estimates can be obtained even without establishing a CLT, by multiplying their widths by 2.3.

On the variety of methods for calculating confidence intervals by bootstrapping.

open access: yesJournal of Animal Ecology, 2015
Researchers often want to place a confidence interval around estimated parameter values calculated from a sample. This is commonly implemented by bootstrapping. There are several different frequently used bootstrapping methods for this purpose.

Wrapping input–output multipliers in confidence intervals

open access: yesJournal of Economic Structures
Input–output multipliers are typically calculated as point estimates of the Leontief quantity model. From the previous literature, they can also be estimated (and their confidence intervals) directly from establishments’/industries’ inputs and outputs ...

What is the Usefulness of Frequentist Confidence Intervals? [PDF]

open access: yesarXiv, 2000
The following questions are discussed: ``Why confidence intervals are a hot topic?''; ``Are confidence intervals objective?''; ``What is the usefulness of coverage?''; ``How to obtain useful information from experiment?''; ``The confidence level must be chosen independently from the knowledge of the data?''.
