The Impact of Plot-Size on the Estimation of Wheat Yield in Sudan: The Case of New-Halfa Agricultural Scheme

Al-Feel, Mohamed Ahmed; Abdullah, Seram Kamal Mohamed - Department of Agricultural Economics, University of Khartoum - 2013

. We use a farm survey data with different plot sizes, in the four villages within the Scheme, and for season 2009 … estimation. However, there were significant differences between large and small plot sizes and between medium and small plot … both strata. As plot size increases, the estimated yield and standard deviation of yield decreases in the two strata. The …

The accuracy of graphs to describe size distributions

González-Val, Rafael; Ramos, Arturo; Sanz-Gracia, Fernando - Volkswirtschaftliche Fakultät, … - 2013

This paper analyses the performance of the graphs traditionally used to study size distributions: histograms, Zipf plots (double logarithmic graphs of rank compared to size) and plotted cumulative density functions. A lognormal distribution is fitted to urban data from three countries (the US,...
