Statistics Covariance Estimation in the Presence of Diverse Types of Data UNIVERSITY OF WASHINGTON Peter D. Hoff NiuXiaoyueA primary goal of multivariate analysis is covariance estimation. Estimating the covariance matrix enables us to study the associations among random variables and provides standard ...

The purpose of this paper is to compare the performances of the three estimation methods in the MIRT framework for tests of mixed item types that have both dichotomous and polytomously scored items, and for tests of mixed structured items (simple structured and complex structured). It is found...

For instance, the optimal rate of parameter estimation in an over-fitted location-covariance Gaussian mixture is precisely determined by the order of a solvable system of polynomial equations --- these rates deteriorate rapidly as more extra components are added to the model. The established rates ...
Distinct types of dorsal root ganglion sensory neurons may have unique contributions to chronic pain. Identification of primate sensory neuron types is critical for understanding the cellular origin and heritability of chronic pain. However, molecular in
