The paper of Bayesian Quantile Regression has been lsited as the `Most Downloaded Statistics & Probability Letters Articles'  since the publication in 2001:

The impact of some of my papers goes out the academic community now as two leading software:

The GAUSS package Qreg (  implemented the methods of Yu and Jones (1998)’;

The SAS package (com/rnd/app/examples/stat/BayesQuantile/quantile.htm) directly detailed my Bayesian model and method of Yu and Moyeed (2001).

1.Case description of Application of DCVG-survey to predict coating defect size on pipelines (2014-2018):

Corrosion activity is hard to model using indirect inspection techniques. For the underground crude oil pipelines operated by NISOC in Iran, in order to identify coating damage, DCVG was performed along these pipelines. Data from pre-assessment, indirect inspection and direct examination (the first three steps of ECDA as specified by NACE) was gathered and analysed. Proper analysis tools and software were produced for companies via TWI (

Case description: to help 5one ( (2013-2014) develop their methods in Transferred Demand to  look at impact on individual product sales: Transferred Demand as defined is the prediction of the movement and substitution of sales from product to product when changes in assortment are made to a category within a grocery retailer (due to a lack of availability or de-listing of a product).
