The new bounds along with Jensen's Inequality may be applied on subsets using the procedures developed by Huang, Ziemba, and Ben-Tal to yield a procedure for obtaining upper and lower bounds on the expectation o
The concepts of a conditional expectation and a 'genuine' regression can be used to describe how the (X=x)-conditional expectation values of a numerical random variable Y depend on the values of a (numerical, non-numerical, multivariate) random variable X. This chapter starts with the ...
The EM algorithm is a two step recursive algorithm that alternates between: 1) computing the expected value of the states of the hidden units given the data and the current values of the parameters, and 2) updating the parameters to maximize the expected log-likelihood. ...
The conditional mean uses information from the previous period and is in general a random variable, depending on the information set Ft−1 and is given by: (1.5)mt≡E[yt|Ft−1]≡Et−1[yt], where yt is the rate of return of a particular stock or market portfolio from time t...
In this paper, a Bayesian-updated expectation-conditional-maximization (ECM) algorithm is adopted to address the uncertainty of prior parameters, and a modified Bayesian-model-averaging method is used to deal with the uncertainty of the degradation model. Then, simulation studies are conducted to ...

The natural choice to describe your conditional distribution for your measured voltage and/or current is a multivariate normal distribution (thanks to the Central Limit theorem). Note that this may not hold with nonlinear circuits, or in linear circuits with feedback. The goal is to de...
with independently measured individual levels of face expertise. Multivariate pattern analysis of the EEG signal revealed clear effects of expectation from 100 ms post stimulus, with significant decoding of the neural response to expected vs. not stimuli, when viewing identical images. Latency of peak...
The simulated dataset 2 was generated by first drawing 500 samples from 3-dimension multivariate normal distribution (i.e., x1, x2, x3) with zero means and randomly generated covariance matrix. Second, we consider the interaction between x1 and x2, x1 and x3, and x2 and x3. Finally, ...
