Abstract : For factorial experiments robust point estimators are proposed for the regression parameters in the two-factor linear regression model. Each estimate is the median of a set of slopes between certain pairs of the design points. The test statistics on which they are based are of the form of Hoeffding's U-statistics. The estimators obey two useful invariance properties and are unbiased. The estimators are also asymptotically normally distributed and asymptotically independent. (Author)
