## Murdaugh Verdict: A Bayesian Perspective

The Murdaugh verdict has been a subject of interest in recent times, with a South Carolina jury finding Alex Murdaugh guilty on two counts of first-degree murder and two counts of weapons possession during a violent crime. This article explores the case from a Bayesian perspective, providing insights into how Bayesian reasoning can be applied …

## Unveiling Asymmetric Quantile Regression in Finance

Quantile regression is an advanced statistical technique that has gained significant attention in finance due to its ability to estimate conditional quantiles. While linear regression is widely used to model the relationship between two variables, it assumes a linear relationship between the dependent variable and the predictors. However, this assumption may not hold in many …

## From Casino Games to Medical Trials: The Real-World Applications of the Central Limit Theorem

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, and presentation of data. The Central Limit Theorem (CLT) is a fundamental concept in statistics that underpins many statistical methods and analyses. It is a powerful tool for analyzing large datasets and predicting outcomes based on limited information. The CLT states that …

## Reducing Bias Due to Differential Dropout Rates

In scientific research, dropout rates refer to the number of participants who leave a study before it is completed. Differential dropout rates are when certain groups of participants are more likely to drop out than others. This phenomenon can have a significant impact on the accuracy and reliability of research findings, as it can …
