This study introduces a novel penalized estimation method tailored for function-on-function regression models, combining the robustness of the Tau estimator with penalization techniques to enhance resistance to outliers. Function-on-function regression is essential for modeling intricate relationships between functional predictors and response variables across diverse fields. However, traditional methods often struggle with outliers, leading to biased estimates and diminished predictive performance. Our proposed approach addresses this challenge by integrating robust Tau estimation with penalization, promoting both robustness and parsimony in parameter estimation. Theoretical foundations of the penalized Tau estimator within function-on-function regression are discussed, along with empirical validations through simulation studies and an empirical data analysis. By incorporating penalization, our method not only ensures robust estimation of regression parameters but also promotes model simplicity, offering enhanced interpretability and generalization capabilities in functional data analysis.

Bu çalışma, fonksiyon-fonksiyon regresyon modellerine yönelik yeni bir cezalandırılmış tahmin yöntemini tanıtmaktadır ve Tau tahmin edicisinin sağlamlığını cezalandırma teknikleriyle birleştirerek aykırı değerlere karşı direnci artırmaktadır. Fonksiyon-fonksiyon regresyon, fonksiyonel bağımsız değişkenler ile yanıt değişkenleri arasındaki karmaşık ilişkileri modellemek için çeşitli alanlarda gereklidir. Ancak geleneksel yöntemler genellikle aykırı değerlerle başa çıkmakta zorlanır ve bu durum yanlı tahminlere ve zayıd tahmin performansına yol açar. Önerilen yaklaşımımız, sağlam Tau tahminini cezalandırma ile birleştirerek bu zorluğun üstesinden gelmekte ve parametre tahmininde hem sağlamlığı hem de tutarlılığı sağlamaktadır. Fonksiyon-fonksiyon regresyon içinde cezalandırılmış Tau tahmin edicisinin teorik temelleri tartışılmakta, simülasyon çalışmaları ve ampirik veri analizleri yoluyla ampirik doğrulamalar sunulmaktadır. Cezalandırmayı dahil ederek, yöntemimiz yalnızca regresyon parametrelerinin sağlam tahminini sağlamakla kalmaz, aynı zamanda modelin basitliğini teşvik ederek fonksiyonel veri analizinde daha iyi yorumlanabilirlik ve genelleme yetenekleri sunar.
