This paper propose the consistent and positive definite correlation matrix based on a Gaussian pseudo-likelihood method and obtain an efficient estimator of the regression parameters for partial linear models with longitudinal data. The estimation algorithm and the method for Gaussian pseudo-likelihood based selection of working covariance models were then given. Simulations show that the parameter estimation based on the Gauss pseudo-likelihood method is efficient.
