1. A method of generating a plurality of weight values associated with respective nodes of a statistical model for use in predicting vision correction prescriptions for patients, the method comprising: obtaining a plurality of wavefront aberration measurements from a plurality of patient's eyes; obtaining a plurality of visual acuity measurements from the plurality of patients; applying values associated with the plurality of wavefront measurements to an input layer of the statistical model; applying values associated with the plurality of visual acuity measurements to an output layer of the statistical model; and generating the plurality of weight values associated with respective nodes of the statistical model based on the applied values associated with the plurality of wavefront measurements and corresponding values associated with the plurality of visual acuity measurements.
