Valuation of patents in emerging economies: a renewal model-based study of Indian patents
Mohd Shadab Danish, Pritam Ranjan, Ruchi Sharma
This study uses patent renewal information to estimate private value of patents by technology and ownership status. Patent value refers to the economic reward that the inventor ext…
Determinants of Patent Survival in Emerging Economies: Evidence from Residential Patents in India
Mohd Shadab Danish, Pritam Ranjan, Ruchi Sharma
The purpose of this paper is to use patent level characteristics to estimate the survival of resident patents (filed at the Indian Patent Office (IPO) and assigned to firms in Indi…
The Evolution of Dynamic Gaussian Process Model with Applications to Malaria Vaccine Coverage Prediction
Pritam Ranjan, M. Harshvardhan
Gaussian process (GP) based statistical surrogates are popular, inexpensive substitutes for emulating the outputs of expensive computer models that simulate real-world phenomena or…
A History Matching Approach for Calibrating Hydrological Models
Natalia V. Bhattacharjee, Pritam Ranjan, Abhyuday Mandal +1
Calibration of hydrological time-series models is a challenging task since these models give a wide spectrum of output series and calibration procedures require significant amount…
A New Class of Discrete-time Stochastic Volatility Model with Correlated Errors
Sujay Mukhoti, Pritam Ranjan
In an efficient stock market, the returns and their time-dependent volatility are often jointly modeled by stochastic volatility models (SVMs). Over the last few decades several SV…
-SELC: Optimization by sequential elimination of level combinations using genetic algorithms and Gaussian processes
Abhyuday Mandal, Pritam Ranjan, C. F. Jeff Wu
Identifying promising compounds from a vast collection of feasible compounds is an important and yet challenging problem in the pharmaceutical industry. An efficient solution to th…
