چکیده

In the standard design approach to missing observations, the construction of weight classes and calibration are used to adjust the design weights for the respondents in the sample. Here we use these adjusted weights to define a Dirichlet distribution which can be used to make inferences about the population. Examples show that the resulting procedures have better performance properties than the standard methods when the population is skewed.

Higher moments portfolio Optimization with unequal weights based on Generalized Capital Asset pricing model with independent and identically asymmetric Power Distribution

The main criterion in investment decisions is to maximize the investors utility. Traditional capital asset pricing models cannot be used when asset returns do not follow a normal distribution. For this reason, we use capital asset pricing model with independent and identically asymmetric power distributed (CAPM-IIAPD) and capital asset pricing model with asymmetric independent and identically a...

Using median regression to obtain adjusted estimates of central tendency for skewed laboratory and epidemiologic data.

BACKGROUND Laboratory studies often involve analyses of highly skewed data for which means are not an adequate measure of central tendency because they are sensitive to outliers. Attempts to transform skewed data to symmetry are not always successful, and medians are better measures of central tendency for such skewed distributions. When medians are compared across groups, confounding can be an...

“No” Is the Easiest Answer: Using Calibration to Assess Nonignorable Nonresponse in the 2002 Census of Agriculture

)))))))))))))))))))))))))))))))))))))))))))))))))))))))))) The 2002 Census of Agriculture adjusted for whole-farm nonresponse by dividing the potential farms on its list into size classes and then weighting the respondents within each class to account for the nonrespondents. Unfortunately, to assign the size-class memberships, a consistent measure of size was needed for all potential farms not ...
