robust
Confidence of estimated result expressed as a value between 0.0 and 1.0. By default 99% of confidence is used, which indicates that with a probability of 99% estimation will be accurate because chosen sub-samples will be inliers (in other terms, outliers will be correctly discarded). This properly is only taken into account if a not-null robustMethod is specified.
Throws
if provided value is not between 0.0 and 1.0 (both included).
