> Summary
> There are several instances where assigning weights to training samples or 
> observations is desirable in order to portray known information about the 
> data or handle situations where data quality varies.  For example, the 
> training sample may have a disproportionate number of observations in certain 
> classes, or the data may have been collected in a stratified manner with one 
> strata having greater or lesser sampling intensity. In such cases, 
> observations can be weighted to reflect the importance of each point in the 
> fitted model.
