WebBackground: It is often important to extrapolate survival estimates beyond the limited follow-up times of clinical trials. Extrapolated survival estimates can be highly sensitive to model choice; thus, appropriate model selection is crucial. Flexible parametric spline models have been suggested as an alternative to standard parametric models; however, their ability to … WebOct 6, 2024 · The way I do extrapolation now is by choosing a set of points in the known part of the curve, fitting a polynomial, and then evaluating this polynomial for values beyond the end of the known curve. Sometimes it looks reasonable, but sometimes it explodes (not unexpectedly for polynomial fitting).
