> 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.
