Back to Tony Cai's Tony Cai and Ming Yuan Abstract: The problem of estimating the mean of random functions based on discretely sampled data arises naturally in functional data analysis. Offers a basic one-term introduction to statistics and also prepares students for STAT 410. After the start of the semester, this document may continue to be updated. We consider both the ideal semi-supervised setting where infinitely many unlabeled samples are available, as well as the ordinary semi-supervised setting in which only a finite Tony Cai, Dong Xia, and Mengyue Zha Abstract: Estimating a covariance matrix and its associated principal components is a fundamental problem in contemporary statistics. We propose an algorithm called HeteroPCA, which involves iteratively imputing the diagonal entries of the sample covariance matrix to remove estimation bias due to heteroskedasticity.
