%description
Machine learning algorithm for predicting and imputing time series. It can
automatically set all the parameters needed, thus in the minimal
configuration it only requires the target variable and the dependent
variables if present. It can address large problems with hundreds or
thousands of dependent variables and problems in which the number of
dependent variables is greater than the number of observations. Moreover
it can be used not only for time series but also for any other real valued
target variable. The algorithm implemented includes a Bayesian stochastic
search methodology for model selection and a robust estimation based on
bootstrapping. 'rego' is fast because all the code is C++.
