úÎ + ïNone8ransac iter sampleSize agreePct fit residual goodFit pts draws  iter samples of size  sampleSize from pts. The fit function E is used to produce a model from each of these samples. The elements  of pts whose residuals pass the goodFit predicate with respect ! to this model are identified as inliers, and used to update the D model. The model for which the size of the inliers set is at least  agreePct9 percent of the entire data set and whose error over all ? points is minimal among all sampled models is returned. If no @ acceptable model is found (i.e. no model whose inliers were at  least agreePct" percent of the entire data set),  is  returned.
