roams provides functions for estimating parameters and detecting outliers in state-space models using the ROAMS (Robust Outlier-Adjusted Mean-Shift) framework. It includes functionality for fitting benchmark models, visualizing model selection criteria, and evaluating in-sample and out-of-sample performance. Simulation tools for generating synthetic data under a first-difference correlated random walk (DCRW) model are also included. Designed with flexibility for user-defined model structures via the specify_SSM() interface.
