Survival trees for right-censored data based on score based parameter instability test
Madan Gopal Kundu, Samiran Ghosh
Survival analysis of right censored data arises often in many areas of research including medical research. Effect of covariates (and their interactions) on survival distribution c…
Robust Variable Selection Criteria for the Penalized Regression
Abhijit Mandal, Samiran Ghosh
We propose a robust variable selection procedure using a divergence based M-estimator combined with a penalty function. It produces robust estimates of the regression parameters an…
Outlier Detection Techniques for SQL and ETL Tuning
Saptarsi Goswami, Samiran Ghosh, Amlan Chakrabarti
RDBMS is the heart for both OLTP and OLAP types of applications. For both types of applications thousands of queries expressed in terms of SQL are executed on daily basis. All the…
Outlier detection from ETL Execution trace
Saptarsi Goswami, Samiran Ghosh, Amlan Chakrabarti
Extract, Transform, Load (ETL) is an integral part of Data Warehousing (DW) implementation. The commercial tools that are used for this purpose captures lot of execution trace in f…
An imputation-based approach for parameter estimation in the presence of ambiguous censoring with application in industrial supply chain
Samiran Ghosh
This paper describes a novel approach based on "proportional imputation" when identical units produced in a batch have random but independent installation and failure times. The cu…
