Understanding JAGS and RunJags: How to Let JAGS Decide on the Adaptation Phase Introduction JAGS (Just Another Gibbs Sampler) is a software for Bayesian inference using Markov Chain Monte Carlo (MCMC) methods. It provides an easy-to-use interface for defining Bayesian models and generating samples from those models. RunJags, on the other hand, is a wrapper around JAGS that simplifies the process of running JAGS models from R. In this article, we will explore how to use RunJags to let JAGS decide on the adaptation phase in Bayesian inference.

Grouping Data by Column and Fixed Time Window/Frequency In the world of data analysis, grouping data by specific columns or time windows is a common task. When dealing with large datasets, it’s essential to find efficient methods that can handle the volume of data without compromising performance. In this article, we’ll explore how to group data by a column and a fixed time window/frequency using various techniques. Introduction The provided Stack Overflow post presents a problem where a user wants to group rows in a dataset based on an ID and a 30-day time window.

Understanding the Cut() Error in R - ‘breaks’ are not unique Introduction The cut() function in R is a powerful tool for dividing a dataset into bins based on continuous data. However, when using the quantile function as part of the cuts, an error can occur if the quantile values are not unique across different levels of the factor. In this article, we will delve into the reasons behind this error and explore ways to resolve it.
