standardize

Sometimes it is desirable to have all variables to have mean 0 and standard deviation 1. This function rescales the values in such a way.
If the argument is not a <code><a href="/link/matrix?package=fDMA&version=2.2.8" data-mini-rdoc="fDMA::matrix">matrix</a></code>, the function tries to convert the object into a <code><a href="/link/matrix?package=fDMA&version=2.2.8" data-mini-rdoc="fDMA::matrix">matrix</a></code>. For example, it works smoothly for <code><a href="/link/xts?package=fDMA&version=2.2.8" data-mini-rdoc="fDMA::xts">xts</a></code> objects.

Allows to estimate dynamic model averaging, dynamic model selection and median probability model. The original methods are implemented, as well as, selected further modifications of these methods. In particular the user might choose between recursive moment estimation and exponentially moving average for variance updating. Inclusion probabilities might be modified in a way using 'Google Trends'. The code is written in a way which minimises the computational burden (which is quite an obstacle for dynamic model averaging if many variables are used). For example, this package allows for parallel computations and Occam's window approach. The package is designed in a way that is hoped to be especially useful in economics and finance.
