## Abstract

For improved estimation of oxygen tension in retinal blood vessels, regularization of least squares estimation method was proposed earlier and it was shown to be very effective. However, closed form solutions for the estimation, and bias and variance of the estimator were not provided and comprehensive statistical analyses were not done. In this chapter, we derive the closed form solution for the regularized least squares estimation, bias and variance of the regularized least squares estimator and with the help of the closed form solutions, statistical performance analyses of the estimator are realized for different values of estimation parameters.
