Hi, Can somebody help recommend some good introductory textbooks on robust estimation (graduate school level)? I found this one, but the reviews on this are quite diverse. http://www.amazon.com/Introduction-Estimation-Hypothesis-Statistical-Modeling/dp/0127515429/ref=sr_1_1?ie=UTF8&s=books&qid=1254970240&sr=8-1 Regards, Peng
