A novel flexible exponent power-X family of distributions with applications to COVID-19 mortality rate in Mexico and Canada.

This paper aims to introduce a novel family of probability distributions by the well-known method of the T-X family of distributions. The proposed family is called a "Novel Generalized Exponent Power X Family" of distributions. A three-parameters special sub-model of the proposed method is derived and named a "Novel Generalized Exponent Power Weibull" distribution (NGEP-Wei for short).

Self-decisive algorithm for unconstrained optimization problems as in biomedical image analysis.

This study describes the construction of a new algorithm where image processing along with the two-step quasi-Newton methods is used in biomedical image analysis. It is a well-known fact that medical informatics is an essential component in the perspective of health care. Image processing and imaging technology are the recent advances in medical informatics, which include image content representation, image interpretation, and image acquisition, and focus on image information in the medical field.

Are these data real? Statistical methods for the detection of data fabrication in clinical trials.

Objectives: To test the application of statistical methods to detect data fabrication in a clinical trial.

Setting: Data from two clinical trials: a trial of a dietary intervention for cardiovascular disease and a trial of a drug intervention for the same problem.

Outcome Measures: Baseline comparisons of means and variances of cardiovascular risk factors; digit preference overall and its pattern by group.

The effect of scientific misconduct on the results of clinical trials: a Delphi survey.

Objectives: To discover what types of scientific misconduct are most likely to influence the results of a clinical trial.

Design: Delphi survey of expert opinion with three rounds of consultation.

Setting: Non-industry clinical trial "community".
