1. Computational GRID for high-performance computation.
2. Data GRID for sharing and administrating large volumes of data.
3. Sensor GRID for real-time monitoring (for example - electronic transactions, traffic and pedestrian flows, environmental features).
4. Access GRID for collaborative visualization involving distant researchers.
The expression "Computational Grid" was coined by analogy with power grids
Its not yet this simple.
SABRE is designed to model recurrent events for a collection of individuals or cases and many other types of repeated measures data with binary, ordinal or count responses. It fits both standard models and various mixture models which allow for residual heterogeneity.
It can be used to fit the following univariate statistical models :
SABRE employs reweighted least squares (standard homogenous models) and Newton-Raphson maximum likelihood (random effects binary models) algorithms. Both algorithms have been parallelised using MPI.
Illustrative data, months to employment dataset contains 3,655,704 monthly observations on 199,881 individuals, with 14,716 non-zero binary outcomes. Comparison uses same starting values. The total number of model parameters = 54.
