A computing device provides graphical interactive b-spline model selection. A presented criterion fit graph includes a number of internal knots line that indicates a number of internal knots value of a determined best fit b-spline model and a polynomial degree curve for each of a set of polynomial degree values. Each polynomial degree curve shows a fit criterion value as a function of the number of internal knot values. A best fit b-spline model graph is presented next to the presented criterion fit graph that includes a knot location line at each of the knot locations of the determined best fit b-spline model and a best fit model curve computed using the coefficients of the determined best fit b-spline model. An indicator that the number of internal knots line is moved to a different number of internal knots value is received. The best fit b-spline model graph is then updated.
