The extent to which products meet specifications needs to be systematically monitored in a production process. Product quality will typically be defined by two quantities: deviations from stated ...

If the expected return on two projects is the same but the second has a higher variance (or standard deviation), then the first will be preferred. Also, if the variance on the two projects is the same ...

We propose a numerical optimization approach that can be used to solve portfolio selection problems including several assets and involving objective functions from cumulative prospect theory (CPT).

Flickr via Google Images Standard deviation is a concept that's thrown around frequently in finance. So what is it? When working with a quantitative data set, one of the first things we want to know ...

Mean and variance of horizontal wind direction are defined in a minimal variance sense. Starting from a theoretical model, termed anisotropic Gaussian model, of the probability density functions of ...
