Fitting the linear preferential attachment model
Preferential attachment is an appealing mechanism for modeling power-law behavior of the degree distributions in directed social networks. In this paper, we consider methods for fitting a 5-parameter linear preferential model to network data under two data scenarios.

High-dimensional shape fitting in linear time [PDF]
Let \(P\) be a set of \(n\) points in \(\Re^d\). The radius of a \(k\)-dimensional flat \({\mathcal F}\) with respect to \(P\), which we denote by \({\mathcal RD}({\mathcal F},P)\), is defined to be \(\max_{p \in P} \text{dist}({\mathcal F},p)\), where \(\text{dist}({\mathcal F},p)\) denotes the Euclidean distance between \(p\) and its projection onto \

Stochastic Design Criteria in Linear Models
Within the framework of classical linear regression model stochastic optimal design criteria are considered. As examples a line fit model and a k-way linear fit model are taken. If the optimal design does not exist, an approach consisting in choosing the
