Estimation is the process of determining a likely value for a population parameter (eg, the true population mean or proportion) based on a random sample. In practice, a sample is drawn from the target population, and sample statistics (eg, the sample mean or sample proportion) are used to generate estimates of the unknown parameter. The sample should be representative of the population, ideally...

This paper studies the design of an optimal relaxed causal sampler using sampled data system theory. A lifted frequency domain approach is used to obtain the existence conditions and the optimal sampler. A state space formulation of the results is also provided. The resulting optimal relaxed causal sampler is a cascade of a linear continuous time system followed by a generalized sampler and a d...

In this paper, we propose a novel tree modeling approach, synthesizing new trees from samples. First, we capture real world trees as samples by image-based modeling or laser scanning techniques. Then, we present a two-level statistical tree model and design a maximum likelihood estimation algorithm to extract it from samples. At the low level in the tree model, groups of similar organs are clus...

Application of recent techniques to detect current pathogens in archival effluent samples collected and concentrated in 1987 lead to the characterization of norovirus GGII.6 Seacroft, unrecognized until 1990 in a clinical sample. Retrospective studies will likely increase our knowledge about waterborne transmission of emerging pathogens.

We consider the problem of approximating the set of eigenvalues of the covariance matrix of a multivariate distribution (equivalently, the problem of approximating the “population spectrum”), given access to samples drawn from the distribution. The eigenvalues of the covariance of a distribution contain basic information about the distribution, including the presence or lack of structure in the...

For the next two weeks, I will discuss some of the concepts of random sample which we use very frequently. These are certainly not the central focus of this course, but it is extremely important for all of us to know these concepts. We have to use these ideas throughout this quarter. First we need to know what do we mean by a random sample. Definition: The random variables X1, ..., Xn together ...
