Astrostatistics, Astroinformatics, and Astro Data Science integrate advanced statistical methods, computational algorithms, and large-scale data analysis to tackle complex astrophysical questions. This group is a professional forum for researchers, data scientists, statisticians, and astrophysicists to collaborate and exchange insights. Topics include time series analysis, machine learning applications, data-driven astrophysical modeling, and large-scale survey interpretation. Members discuss best practices for data handling, algorithm optimization, Bayesian inference, neural networks, software development, data visualization, and interdisciplinary applications in space missions and observatories.
