ECONOMICS OF MALWARE: SECURITY DECISIONS, INCENTIVES AND EXTERNALITIES (2009)

English Or. English, Johannes M. Bauer, Johannes M. Bauer, Tithi Chattopadhyay, ...

to make available to a wider readership selected studies prepared by staff in the Directorate or by outside consultants working on OECD projects. The papers included in the series cover a broad range...

Tuning parameter selection for penalized likelihood estimation of inverse covariance matrix (2009)

Gao, Xin, Pu, Daniel Q., Wu, Yuehua, Xu, Hong

In a Gaussian graphical model, the conditional independence between two variables are characterized by the corresponding zero entries in the inverse covariance matrix. Maximum likelihood method using...

Strong Consistency and Exponential Rate of the 'Minimum L1-Norm' Estimates in Linear Regression Models. (1998)

Wu, Yuehua

This document considers a linear regression model, where (x sub i) is a sequence of experimental points, i. e., known p-vectors, (e sub i) is a sequence of independent random errors, with med(e sub...

Strong Consistency of Estimation of Number of Regression Variables when the Errors are Independent and Their Expectations are not Equal to Each Other. (1998)

Wu, Yuehua

This document considers the linear regression model y sub i = x sub i B + e sub i, i = 1, 2, ..., where (x sub i) - is a sequence of known p-vectors, Beta = (Beta Sub 1, ..., Beta Sub p) is an...

Strong Law for Mixing Sequence. (1998)

Chen, Xiru, Wu, Yuehua

This document presents some theorems on the strong law for the mixing sequence which is not necessarily stationary, and the mixing coefficient involving only a pair of variables in the sequence....

Discrimination Analysis when the Variates are Grouped and Observed in Sequential Order, (1998)

Wu, Yuehua

Suppose that measurements x sub i = (x sub i sub 1, ...,X sub i sub j sub i), i = 1,...,k, can be taken on a unit sequentially in that order at the prescribed costs Ci, i = 1,...,k. The unit comes...

A strongly consistent procedure for model selection in a regression problem (1989)

RAO, RADHAKRISHNA, WU, YUEHUA

We consider the multiple regression model Yn= Xnβ+ En, where Yn and En are n-vector random variables, Xn is an n�m matrix and β is an m-vector of unknown regression parameters. Each component of...

The simultaneous estimation of the number of signals and frequencies of multiple sinusoids when some observations are missing: I. Asymptotics

Bai, Zhidong, Rao, Calyampudi R., Wu, Yuehua, Zen, Mei-Mei, Zhao, Lincheng

The problem of simultaneous estimation of the number of signals and frequencies of multiple sinusoids is considered in the case when some observations are missing. The number of signals is estimated...

Strong convergence rate of estimators of change point and its application

Shi, Xiaoping, Wu, Yuehua, Miao, Baiqi

Let {Xn,n[greater-or-equal, slanted]1} be an independent sequence with a mean shift. We consider the cumulative sum (CUSUM) estimator of a change point. It is shown that, when the rth moment of Xn is...
