We use artificial data sets to perform large-scale experiments in order to validate the accuracy of the time delay estimation in gravitational lens systems. We generate simulated data sets with different levels of noise, varying the size and location of observational gaps. We present a new approach to estimating the time delay, which is based on generalised linear Kernel Regression. We compare results with the most popular methods.
