The effect of these measures on total … employment is ambiguous in the model. Simulations show that there are cases when reduction of the unemployment benefits …

Mean duration of unemployment is close to fouryears …With around 50% of the urban men between age 15 and 30 unemployed, Ethiopia has one of the highest unemployment rates …

estimation of bias and standard error under simple randomsampling and complex sampling. Three con dence intervals are discussed … complex sampling. It begins by looking at sampling in general withspecific focus on complex sampling and weighting. For the … estimation of the welfareindices, two resampling techniques, viz. jackknife and bootstrap, are discussed.They are used for the …

Systematic sampling is easy, efficient, and widely used, though it is not generally recognized that a systematic sample … of them determine which estimators are unbiased, when using the sampling design as the basis for inference. We describe … selection. When the population size is known at the outset, systematic sampling with unrestricted selection is most likely the …

The line intersect estimator used with those … samples requires a measurement of the quadratic mean diameter (QMD). Published information regarding appropriate QMDs by FWD …

Binomial sampling based on the proportion of samples infested was investigated for estimating mean densities of citrus … parameters adequately described a validation data set from a sampling plan consisting of 192 samples. Projections indicated the … fitted parameters would apply to sampling plans with as few as 48 samples, but reducing sample size resulted in an increase …
