REGRESSIONanalysisHETEROGENEITYANALYSISThis paper studies the influence diagnostics in meta-regression model including case deletion diagnostic and local influence analysis. We derive the subset deletion formulae for the estimation of regression coefficient and heterogeneity variance and obtain the corresponding ...
In this article, we proposed some influence diagnostics for the gamma regression model (GRM) and the gamma ridge regression model (GRRM). We assess the impact of influential observations on the GRM and GRRM estimates by extending the work of Pregibon [Logistic regression diagnostics. Ann Stat. ...

Regression diagnosticsShrinkageThe increased availability of high-dimensional data, and appeal of a "sparse" solution has made penalized likelihood methods commonplace. Arguably the most widely utilized of these methods is regularization, popularly known as the lasso. When the lasso is applied to high-...
In this paper we introduce some influence diagnostics in regression in complex survey. They are built on the conditional bias concept (Moreno-Rebollo et al., 1999). We emphasize the similarities and differences of the proposed measures with respect to the existing ones for the i.i.d. case....
function,this paper develops the local influence analysis of the zero inflated poisson regression models under the the case-weights,perturbation of explanatory variables and response,respectively,and the corresponding diagnostics statistics are obtained.Finally,a numerical example is given to illustrate the ...
