LAND TENURE AND OFFICIAL STATISTICS: A RESEARCH NOTE*

Journal of Agricultural Economics, 1977
In recent years there has been a great deal of discussion in the social sciences concerning the use of official statistics. This research note takes the case of official land tenure statistics, and, on the basis of material gathered in interviews with farmers in East Anglia, shows how these statistics are both technically and conceptually weak and fail

Statistical land clutter modeling for airborne radar

Proceedings of ICICS, 1997 International Conference on Information, Communications and Signal Processing. Theme: Trends in Information Systems Engineering and Wireless Multimedia Communications (Cat. No.97TH8237), 2002
This paper presents a new approach for modeling the radar land clutter, by considering broad regions of ground and all types of roughness. In this way, many kinds of terrains with and without mountains and their composite forms are taken into account. Finally a generalized probability density function is introduced for the envelope of the clutter.

Statistical Modeling and Analysis of Landing Time Intervals

Transportation Research Record: Journal of the Transportation Research Board, 2005
Existing literature suggests that analyses of landing time intervals employ simple statistical models based on time-separation histograms, usually approximated by normal distributions. Although the literature focuses on important issues such as safety, capacity improvements, and separation rules, it does not take into account another important issue ...

Statistical Study of Aircraft Landing-Noise Levels

The Journal of the Acoustical Society of America, 1970
Recent work related to the aircraft noise problem has presented the opportunity to obtain a great deal of measured data of the landing noise produced by present day jet aircraft. The quantity of the measured data allows a statistical evaluation of the results.

Certainties and uncertainties of land cover statistics in China.

Journal of environmental sciences (China), 2004
Vegetation or land cover maps have been made directly or indirectly available for the entire territory of China. The certainties and uncertainties of land cover statistics were analyzed by comparing three data sources: China's Vegetation Map, IGPB DISCover, and University of Maryland Product.
