Classical methods of DOA estimation such as the MUSIC algorithm are based on estimating the signal and noise subspaces from the sample covariance matrix. For a small number of samples, such methods ...

To reinforce this recommendation, we outline seven reasons why inadequate sample size negatively affects model training, evaluation, and performance. Using a range of examples, we illustrate these ...

For example, a study on predicting cervical cancer screening uptake emphasised that sample size calculations were irrelevant for their purpose because classification and regression tree (CART) ...

A new study offers a framework to estimate the sample size required for microbiome association studies based on expected effect sizes and analysis methods. By utilizing two large datasets ...

We sought to develop a similar nomogram to estimate sample size in diagnostic trials based upon determination of sample size precision. We present nomograms for the prospective calculation of sample ...

The importance of estimating sample sizes is rarely understood by researchers, when planning a study. This paper aims to highlight the centrality of sample size estimations in health research.

The factors that affect the precision of an estimate include the level of confidence (Higher levels of confidence result in wider intervals), the variability of the point estimate (More variability ...

Explore how increasing sample size reduces standard error, enhancing statistical estimates' accuracy and reliability in data analysis.

Minimum sample size for estimating the Net Promoter Score under a Bayesian approach Authorship SCIMAGO INSTITUTIONS RANKINGS Abstract Text Introduction Frequentist approach Bayesian approach ...
