What are splines in statistics?
A spline is a continuous function which coincides with a polynomial on every subinterval of the whole interval on which is defined. In other words, splines are functions which are piecewise polynomial. The coefficients of the polynomial differs from interval to interval, but the order of the polynomial is the same.
What are penalized splines?
Penalized splines, or P-splines, are regression splines fit by least-squares with a roughness penalty. P-splines have much in common with smoothing splines, but the type of penalty used with a P-spline is somewhat more general than for a smoothing spline.
How do splines work?
The spline bends a sheet of rubber that passes through the input points while minimizing the total curvature of the surface. It fits a mathematical function to a specified number of nearest input points while passing through the sample points.
What is a restricted cubic spline?
A restricted cubic spline is a cubic spline in which the splines are constrained to be linear in the two tails. This generally provides a better fit to the data, and also has the effect of reducing the degrees of freedom.
Can you use splines in logistic regression?
Be careful using simple linear logistic regression! It may miss out on non-linear features, and it has issues with correlation among predictors. Splines are a way to fit non-linear features and the LRT (Likelihood Ratio Test) can tell you the impact of removing higher order splines from model.
