In this paper, a weighted link-specific (WLS) approach is proposed for high-dimensional Poisson and Gamma regression, providing a unified statistical inference framework. By regressing the parameter deviations and initial estimation errors, the resulting regression coefficients are utilized as correction weights to decrease the total mean square error (MSE). Additionally, the asymptotic normality of the correction estimates is developed under sparse and non-sparse conditions, and associated confidence intervals (CIs) are constructed to verify the robustness of the new method. Numerical simulations and empirical analysis demonstrate the extensive and effective nature of the WLS method.
