Di64256erentiating 8706S 8706f Setting the partial derivatives to 0 produces estimating equations for the regression coe64259cients Because these equations are in general nonlinear they require solution by numerical optimization As in a linear model. By scattered data we mean an arbitrary set of points in which carry scalar quantities ie a scalar 64257eld in dimensional parameter space In contrast to the global nature of the leastsquares 64257t the weighted local ap proximation is computed eithe 21 of the text describes in some detail how objects are located along the search path in R and SPLUS I believe that the material presented there su64259ces for the everyday use of S in data analysis Elsewhere in the text for example in describing lo The prototypical such event is death from which the name survival analysis and much of its terminology derives but the ambit of application of survival analysis is much broader Essentially the same methods are employed in a variety of disciplines un The parameters of the model are the regression coe64259cients andtheerrorvariance Usually 1 andso isaconstantorintercept For comparisonwiththe linearmixedmodel ofthenextsection I rewrite the linear model inmatrix form where y y istheresponsevec Professor William Greene.
