Error Propagation in Isometric Log-ratio Coordinates for Compositional Data: Theoretical and Practical Considerations
Compositional data, as they typically appear in geochemistry in terms of concentrations of chemical elements in soil samples, need to be expressed in log-ratio coordinates before applying the traditional statistical tools if the relative structure of the data is of primary interest. There are different possibilities for this purpose, like centered log-ratio coefficients, or isometric log-ratio ...
متن کاملPractical aspects of federalizing disaster response
On 25 September 2005, the US President, responding to growing criticism of the response to Hurricane Katrina, said ‘... is there a natural disaster – of a certain size – that would then enable the Defense Department to become the lead agency in coordinating and leading the response effort? That’s going to be a very important consideration for Congress to think about.’ [1]. Five days later his b...
متن کاملBinary Regression With a Misclassified Response Variable in Diabetes Data
Objectives: The categorical data analysis is very important in statistics and medical sciences. When the binary response variable is misclassified, the results of fitting the model will be biased in estimating adjusted odds ratios. The present study aimed to use a method to detect and correct misclassification error in the response variable of Type 2 Diabetes Mellitus (T2DM), applying binary ...
متن کاملScaling Connectionist Compositional Representations
The Recursive Auto-Associative Memory (RAAM) has come to dominate connectionist investigations into representing compositional structure. Although an adequate model when dealing with limited data, the capacity of RAAM to scale-up to real-world tasks has been frequently questioned. RAAM networks are difficult to train (due to the moving target effect) and as such training times can be lengthy. I...
متن کاملNonparametric regression on functional data: inference and practical aspects
We consider the problem of predicting a real random variable from a functional explanatory variable. The problem is attacked by mean of nonparametric kernel approach which has been recently adapted to this functional context. We derive theoretical results by giving a deep asymptotic study of the behaviour of the estimate, including mean squared convergence (with rates and precise evaluation of ...
