PRASAD, Shakti  e  YADAV, Vinay Kumar. Imputation of Missing Data Through Product Type Exponential Methods in Sampling Theory. Rev.Colomb.Estad. [online]. 2023, vol.46, n.1, pp.111-127.  Epub 18-Jan-2023. ISSN 0120-1751.  https://doi.org/10.15446/rce.v46nl.102308.

Some efficient product type exponential imputation methods are pro-posed in this article to tackle the problem of incomplete values in sampling theory. To investigate the effectiveness of proposed exponential methods, the behaviours of the considered estimators are compared in two scenarios: with and without nonresponse. The simulation studies show that the proposed resultant estimators outperform other existing estimators in this literature.
