Every machine degrades with time and requires maintenance. Among all types of maintenance policies, predictive maintenance is established as the best form of maintenance policy as numerous benefits are associated with it. Despite all the benefits, it finds restrictive usage in manufacturing...

This paper proposes a predictive maintenance policy using modified failure mode effect and criticality analysis (Mod-FMECA) technique. FMECA is used to identify failure modes, reasons, effects and criticality of the system (machine/plant) but in Mod-FMECA in addition to the analysis carried for...

In this paper, we construct confidence sets for models defined by many conditional moment inequalities/equalities. The conditional moment restrictions in the models can be finite, countably in finite, or uncountably in finite. To deal with the complication brought about by the vast number of...

I show that a congruent, parsimonious, encompassing model discovered using David Hendry's econometric modelling approach and Autometrics can overcome the many inadequacies of the typical static models of US Treasury returns regressed on macroeconomic announcements. The typical specification...

Building on realized variance and bi-power variation measures constructed from high-frequency financial prices, we propose a simple reduced form framework for effectively incorporating intraday data into the modeling of daily return volatility. We decompose the total daily return variability...

Marketing mix modeling has existed for decades now. Everyone has been using it, some tapped its potential with enormous success while others are yet to see its true potential. Rapidly changing marketing environment, consumer dynamics and multi touch points have made it even more complex to get...

In this paper, we recognize that reigning econometric paradigms, do not provide a basis for understanding the complex economic behavioral processes and systems. To acknowledge this void, we borrow some of the key fundamental concepts of entropy methods, and non equilibrium physical systems...

The following document outlines a technique for pricing interest rate swaps in terms of the underlying asset exposures and the internal yield to maturity of the contract. Hence, you can use the Par Yield as opposed to the entire Zero Curve, since the Par Yield implicitly embeds the Curve at the...

This paper presents the staggered difference-in-differences (DiD) method in an accessible language to a broad accounting research audience from an applied researcher's perspective. Specifically, the paper examines DiD design problems when multiple units are treated and when the treatment is...
