Proportional cross-ratio model

Cross-layer Packet-dependant OFDM Scheduling Based on Proportional Fairness

This paper assumes each user has more than one queue, derives a new packet-dependant proportional fairness power allocation pattern based on the sum of weight capacity and the packet’s priority in users’ queues, and proposes 4 new cross-layer packet-dependant OFDM scheduling schemes based on proportional fairness for heterogeneous classes of traffic. Scenario 1, scenario 2 and scenario 3 lead r...

Proportional odds ratio model for comparison of diagnostic tests in meta-analysis

BACKGROUND Consider a meta-analysis where a 'head-to-head' comparison of diagnostic tests for a disease of interest is intended. Assume there are two or more tests available for the disease, where each test has been studied in one or more papers. Some of the papers may have studied more than one test, hence the results are not independent. Also the collection of tests studied may change from on...

177-30: Using SAS® to Estimate Proportional Odds Ratio Model for Meta-Analysis of Diagnostic Tests

This work shows how we can use SAS system to implement the proportional odds ratio (POR) model (Siadaty 2004). POR is used to pool results of several studies together in a meta-analysis of diagnostic tests. It generalizes comparison of competing tests when there are two or more tests available for disease and each test has been studied in one or more papers and each paper might have studied mor...

Model Diagnostics for Proportional and Partial Proportional Odds Models

Cross Ratio Graphs

A family of arc-transitive graphs is studied. The vertices of these graphs are ordered pairs of distinct points from a finite projective line, and adjacency is defined in terms of the cross ratio. A uniform description of the graphs is given, their automorphism groups are determined, the problem of isomorphism between graphs in the family is solved, some combinatorial properties are explored, a...
