The P value and statistical significance: Misunderstandings, explanations, challenges, and alternatives

open access: yesIndian Journal of Psychological Medicine, 2019
The calculation of a P value in research and especially the use of a threshold to declare the statistical significance of the P value have both been challenged in recent years.

A self‐normalized approach to confidence interval construction in time series [PDF]

open access: yes, 2010
Summary.  We propose a new method to construct confidence intervals for quantities that are associated with a stationary time series, which avoids direct estimation of the asymptotic variances.

Simultaneous Confidence Intervals for Pairwise Differences of Means in Zero-Inflated Rayleigh Distributions with an Application to Road Accident Fatalities Data

open access: yesMathematics
This paper develops simultaneous confidence intervals (SCIs) for pairwise differences of means with zero-inflated Rayleigh (ZIR) distributions, a flexible framework for modeling positively skewed data with excess zeros.

Confidence intervals for the difference and the ratio of Lognormal means with bounded parameters [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2015
In this paper, confidence intervals for the difference between lognormal means and the ratio of lognormal means with restricted parameter spaces are proposed.

Empirical methods for the validation of time-to-event mathematical models taking into account uncertainty and variability: application to EGFR + lung adenocarcinoma

open access: yesBMC Bioinformatics, 2023
Background Over the past several decades, metrics have been defined to assess the quality of various types of models and to compare their performance depending on their capacity to explain the variance found in real-life data.

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.

Secure and Usable Bio-Passwords based on Confidence Interval [PDF]

open access: yesJournal of Internet Services and Information Security, 2017
The most popular user-authentication method is the password. Many authentication systems try to enhance their security by enforcing a strong password policy, and by using the password as the first factor, something you know, with the second factor being ...
