"Arma" most likely refers to the model, a foundational statistical tool used in time-series analysis to predict future data points based on past observations.

Discusses why standard software often yields sub-optimal estimates and provides a more robust framework for modern statistical practice.

ARMA models are used across fields to forecast everything from solar energy to heart health.

Introduces a new class of models specifically for data that must be whole numbers (integers), such as population counts or financial transactions. ๐ŸŒ Diverse Applications
