A simple analytical approach to deal with unobserved feeding in lifetime measurements using a plunger method [PDF]
Determination of lifetime of low-lying states using a plunger method could be a subject of systematic uncertainty if, among else, correction of unobserved feeding is not properly taken into account. In this paper, a simple analytical approach is

On the Automatic Identification of Unobserved Components Models [PDF]
Automatic identi cation of time series models is a necessity once the big data era has come and is staying among us. This has become obvious for many companies and public entities that has passed from a crafted analysis of each individual problem to handle a tsunami of information that has to be processed e ciently, online and in record time ...

On Finite and Non-Finite Bayesian Mixture Models
In this paper, a Bayesian paradigm of a mixture model with finite and non-finite components is expounded for a generic prior and likelihood that can be of any distributional random noise.

TESTING STATIONARITY WITH UNOBSERVED-COMPONENTS MODELS [PDF]
In the aftermath of the global financial crisis, competing measures of the trend in macroeconomic variables such as U.S. real GDP have featured prominently in policy debates. A key question is whether large shocks to macroeconomic variables will have permanent effects—i.e., in econometric terms, do the data contain stochastic trends?

Fitting Time Series Models to Fisheries Data to Ascertain Age
The ability of government agencies to assign accurate ages of fish is important to fisheries management. Accurate ageing allows for most reliable age-based models to be used to support sustainability and maximize economic benefit. Assigning age relies on

Signal extraction and the formulation of unobserved components models [PDF]
Summary: This paper looks at unobserved components models and examines the implied weighting patterns for signal extraction. There are four main themes. The first concerns the implications of correlated disturbances driving the components, especially those cases in which the correlation is perfect.
