Table 2.

Best regression model obtained for the use of longitudinal data and specified input and output. The table shows Support Vector Machines SVM as the best model.

Longitudinal data
Given number	Input	Best regression (from 19 trained)	Output (at age+n)
3	Age, gender, sphere	SVR—Linear R2: 0.57 RMSE: 0.09 D	AxL/Cr
4	Age, gender, AxL/Cr	SVM—Quadratic R2: 0.57 RMSE: 1.33 D	Sphere
5	Age, gender, sphere	SVR—Linear R2: 0.77 RMSE: 0.97 D	Sphere

Axl/Cr, axial length to corneal radius ratio; D, diopter; R², coefficient of determination; RMSE, root mean squared error; SVM-Quadratic, quadratic support vector machine; SVR, linear support vector regression.
