MLwiN 2.1

It is a software package for fitting multilevel models.
Main features:
- Names window (where you can see all the variables)
- Equations window (showing what model has been fitted and the parameter estimates). More >>
- Variance function window (to calculate the residual variance at any level)
- Predictions window (to calculate predicted values for each individual in the dataset, specifying what should be included in the prediction), and
- Graphs (here the user has clicked on the country line that seems to be different from the others and asked that points relating to this country be drawn in red in all graphs, to help in deciding whether this is an outlier; the country is the Netherlands, as the user would have seen when they clicked on the line).
