The problem of inference about the joint distribution of two categorical variables based on knowledge or observations of their marginal distributions, to be referred to as categorical data fusion in this paper, is relevant in statistical matching, ecological inference, market research, and several other related fields. This article organizes the use of proxy variables, to be distinguished from ...

Environmental risk assessment is typically uncertain due to different perceptions of the risk problem and limited knowledge about the physical, chemical, and biological processes underlying the risk. The present paper provides a systematic overview of the implications of different types of uncertainty for risk management, with a focus on risk-based management of river basins. Three different ty...

The paper investigates the effects of uncertainty shocks in emerging economies (EMEs). We construct a global indicator as well country measures for fifteen relatively small economies. adopt an instrumental variable approach to identify exogenous EMEs. To deal with data limitations specific countries, we develop new Bayesian algorithm estimate proxy panel structural vector autoregressive (SVAR) ...

An evolved version of the Technology Identification, Evaluation, and Selection (TIES) method is presented that provides techniques for quantifying technological uncertainty associated with immature technologies. Uncertainty in this context implies forecasting. Forecasting the impact of immature technologies on a system is needed to provide increased knowledge to a decision-maker in the conceptu...
