Often the time derivative of a measured variable is of as much interest as the variable itself. For a growing population of biological cells, for example, the population’s growth rate is typically ...

Methods for simulation from multivariate Gaussian distributions restricted to be from outside an arbitrary ellipsoidal region are often needed in applications. A standard rejection algorithm that ...

Data in statistical practice often consist of nonnegative measurements that exhibit positive skewness. The inverse Gaussian (IG) family of distributions provides a versatile and flexible model for ...

All sorts of physical processes in this analog world exhibit some degree of randomness. Think of noise, for example. Many noisy processes are described by Gaussian probability distributions. We should ...

A bell curve is a graph used to visualize the distribution of a set of chosen values across a specified group that tend to have central, normal values that peak, with low and high extremes tapering ...

The Inverse Sampling Method can expand the capability of tools, such as Excel and Spice, into performing user-defined statistical simulations. Not all Spice versions perform Monte Carlo simulations.

The use of Statistical Process Control (SPC) in compliance under GLP offers market opportunities. By utilizing control charts and statistical guidelines like Nelson Rules, laboratories can proactively ...
