摘要：

This　paper　considers　robust　estimation　of　varying　coefficient　models　with　emphasis　on　resistance　against　outliers.　By　combining　B-splines　method　with　taut　string　method,　a　robust　estimation　procedure　is　proposed.　Based　on　local　quadratic　approximation,　an　iterative　algorithm　is　introduced.　Simulation　study　indicates　that　the　proposed　method　is　robust.
