Profile Likelihood and Incomplete Data [PDF]

open access: yesInternational Statistical Review, 2010
Summary According to the law of likelihood, statistical evidence is represented by likelihood functions and its strength measured by likelihood ratios. This point of view has led to a likelihood paradigm for interpreting statistical evidence, which carefully distinguishes evidence about a parameter from error probabilities and personal belief.

Textually Summarising Incomplete Data [PDF]

open access: yesProceedings of the 10th International Conference on Natural Language Generation, 2017
Many data-to-text NLG systems work with data sets which are incomplete, ie some of the data is missing. We have worked with data journalists to understand how they describe incomplete data, and are building NLG algorithms based on these insights. A pilot evaluation showed mixed results, and highlighted several areas where we need to improve our system.

Phase Identification With Incomplete Data

open access: yesIEEE Transactions on Smart Grid, 2018
Phase identification is a process to determine which of the three phases a particular house is connected to. The state-of-the-art identification methods usually exploit smart metering data. However, the data sets are not always available and the major challenge is hence to identify phases with incomplete data set.

Comparison of Algorithms for Clustering Incomplete Data

open access: yesFoundations of Computing and Decision Sciences, 2014
The missing values are not uncommon in real data sets. The algorithms and methods used for the data analysis of complete data sets cannot always be applied to missing value data.

Unsupervised and Supervised Feature Selection for Incomplete Data via L2,1-Norm and Reconstruction Error Minimization

open access: yesApplied Sciences, 2022
Feature selection has been widely used in machine learning and data mining since it can alleviate the burden of the so-called curse of dimensionality of high-dimensional data.

Classification of Incomplete Data Based on Evidence Theory and an Extreme Learning Machine in Wireless Sensor Networks

open access: yesSensors, 2018
In wireless sensor networks, the classification of incomplete data reported by sensor nodes is an open issue because it is difficult to accurately estimate the missing values.

Correlating variables with different scale types: A new framework based on matrix comparisons

open access: yesMethods in Ecology and Evolution, 2023
Ecological variables may be expressed on four basic measurement scales (nominal, ordinal, interval or ratio), whereas circular variables and those combining a nominal state with other scale types are also common.

Uncovering Suspicious Activity From Partially Paired and Incomplete Multimodal Data

open access: yesIEEE Access, 2017
Multimodal data can be used to gain additional perspective on a phenomenon. For applications, such as security and the detection of suspicious activity, the need to aggregate and analyze data from multiple modes is vital.

Central Nervous System Neuroblastoma, FOXR2‐Activated: A Pooled Analysis of Published Clinical Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) neuroblastoma, FOXR2‐activated, is a recently recognized entity in the WHO CNS5 classification, defined by activation of the FOXR2 transcription factor and unique histopathological features. This review synthesizes available literature and pooled clinical data, providing insight into demographics ...

On econometric modeling of incomplete data [PDF]

open access: yesMethods of Operations Research, 1985
We discuss results on identification and estimation of dynamic models when values of the endogenous variable are regularly missing. The available data are assumed to be sampled at regular intervals of length k and can be linear combinations of the realizations of the variable over a finite number of periods.
