Bootstrap Resampling of Temporal Dominance of Sensations Curves to Compute Uncertainties

open access: yesFoods, 2021
In the last decade, temporal dominance of sensations (TDS) methods have proven to be potent approaches in the field of food sciences. Accordingly, thus far, methods for analyzing TDS curves, which are the major outputs of TDS methods, have been developed.

Variance Inflation Due to Censoring in Survival Probability Estimates

open access: yesStatistica, 2021
One of the most obvious features of time-to-event data is the occurrence of censoring. Rarely, if ever, studies are conducted until all participants experience the event of interest.

Estimation of confidence intervals for decompositions and other complex demographic estimators

open access: yesDemographic Research, 2023
Background: While the use of standard errors and confidence intervals is common in regression-based studies in the population sciences, it is far less common in studies using formal demographic measures and methods, including demographic decompositions.

Standard deviations and standard errors [PDF]

open access: yesBMJ, 2005

Accurate Standard Errors in Multilevel Modeling with Heteroscedasticity: A Computationally More Efficient Jackknife Technique

open access: yesPsych, 2023
In random-effects models, hierarchical linear models, or multilevel models, it is typically assumed that the variances within higher-level units are homoscedastic, meaning that they are equal across these units. However, this assumption is often violated
