Book
Regression Analysis: Theory, Methods, and Applications
Ashish Sen,Muni S. Srivastava +1 more
TL;DR: An up-to-date, rigorous, and lucid treatment of the theory, methods, and applications of regression analysis, and thus ideally suited for those interested in the theory as well as those whose interests lie primarily with applications.
Book
Gravity Models of Spatial Interaction Behavior
Ashish Sen,Tony E. Smith +1 more
TL;DR: In this paper, the authors propose a framework for the analysis of spatial interaction processes in the context of gravity models, including the following: 1.1 Measures of Spatial Separation, 1.2 Relaxation of Locational Independence, and 1.3 Structural Independence.
Journal ArticleDOI
On Tests for Detecting Change in Mean
Ashish Sen,Muni S. Srivastava +1 more
TL;DR: In this article, the means of each variable in a sequence of independent random variables can be taken to be the same, against alternatives that a shift might have occurred after some point $r$.
Journal ArticleDOI
Frequency of probe reports and variance of travel time estimates
TL;DR: Using probe travel time data from a set of signalized arterials, it is shown that a is positive for well-traveled signalized links, implying that the variance of the mean of travel times obtained from n probes for the same link over a fixed time period does not go to zero with increasing n.
Journal ArticleDOI
Some One-Sided Tests for Change in Level
Ashish Sen,Muni S. Srivastava +1 more
TL;DR: In this paper, a simple application using traffic accident data is presented, where Bayesian tests as well as a test based on the maximum likelihood estimate of γ are considered and their powers are compared by Monte Carlo methods.
