This paper describes the application of the Test Automation Framework (TAF) on the Mars Polar Lander (MPL) software. The premature shutdown of the descent engine on the MPL spacecraft is believed to be the most likely cause for the mission failure. It is believed that the engine shutdown occurred when the three landing legs were extended into their deployed(More)
We consider a semiparametric estimation method for general regression models when some of the predictors are measured with error. The technique relies on a kernel regression of the \true" covariate on all the observed covariates and surrogates. This requires a nonparametric regression in as many dimensions as there are covariates and surrogates. The usual(More)
