Researchers have developed a new estimator for invariance learning that can handle missing outcome data, a common challenge in real-world scenarios. This method aims to improve model generalization and capture stable, potentially causal relationships even when data collection is difficult. The estimator provides theoretical guarantees on variable selection and error convergence, with performance influenced by the extent of missing data and imputation quality. Evaluations on simulations and the UCI Bike Sharing dataset showed the estimator's efficiency and ability to achieve lower prediction error. AI
