IS THE SAMPLE COEFFICIENT OF VARIATION A GOOD ESTIMATOR FOR THE POPULATION COEFFICIENT OF VARIATION?

Mahmoudvand, Rahim; Hassani, Hossein; Wilson, Rob - Volkswirtschaftliche Fakultät, … - 2007

In this paper, we obtain bounds for the population coefficient of variation (CV) in Bernoulli, Discrete Uniform, Normal … and Exponential distributions. We also show that the sample coefficient of variation (cv) is not an accurate estimator of …

A Poverty Analysis in Baitadi District, Rural Far Western Hills of Nepal: An Inequality Decomposition Analysis

Maharjan, Keshav Lall; Joshi, Niraj Prakash - Volkswirtschaftliche Fakultät, … - 2007

Occupational caste is deprived in terms of education, and landholding. Due to this laboring and agriculture (specially small animals like goats and poultry) remain the prominent source of income for them. Average income from salaried job is the highest followed by remittance and that from...

On the existence of a normal approximation to the distribution of the ratio of two independent normal random variables

Díaz-Francés, Eloísa; Rubio, Francisco - In: Statistical Papers 54 (2013) 2, pp. 309-323

The distribution of the ratio of two independent normal random variables X and Y is heavy tailed and has no moments. The shape of its density can be unimodal, bimodal, symmetric, asymmetric, and/or even similar to a normal distribution close to its mode. To our knowledge, conditions for a...

Effect of surface wave inversion non-uniqueness on 1D seismic ground response analysis

Roy, Narayan; SankarJakka, Ravi; Wason, H. - In: Natural Hazards 68 (2013) 2, pp. 1141-1153

Surface wave methods are increasingly being used for geotechnical site characterization. The methodology is based on the dispersive characteristic of Rayleigh waves in vertically heterogeneous medium. Experimental dispersion curve is inverted to obtain one-dimensional shear-wave velocity profile...
