Figure 1: Likelihood-based methods are less accurate than maximum parsimony (MP) under heterogeneous conditions. Figure 2: Parsimony outperforms likelihood over a wide range of heterotachous ...

Value-at-risk (VaR) is one of the most common risk measures used in finance. The correct estimation of VaR is essential for any financial institution, in order to arrive at the accurate capital ...

There are times to design with parametric features and times to work with free-form versions. A few advantages of designing in 3D solids include associative detail drawings, creating complex features, ...

We conduct a comprehensive study of some parametric models that are designed to fit the unusual bounded and bimodal distribution of loss given default (LGD). We first examine a smearing estimator, a ...

Analysis of variance is sensitive to the distribution of the error term. If the error term is not normally distributed, the statistics based on normality can be ...

Parametric tests make assumptions that aspects of the data follow some sort of theoretical probability distribution. Non-parametric tests or distribution free methods do not, and are used when the ...
