measure_variance_explained

Metrics are functions that tell how much information would be
lost for a given reduction in the data. reduce. <code>as_measure()</code> is a
helper function to create new metrics to be used in <code>partitioner</code>s.
<code>partitioner</code>s can be created with <code>as_partitioner()</code>.
<code>measure_variance_explained()</code> assesses information loss by calculating the
variance explained by the first component of a principal components analysis.

A fast and flexible framework for agglomerative partitioning.
'partition' uses an approach called Direct-Measure-Reduce to create
new variables that maintain the user-specified minimum level of
information. Each reduced variable is also interpretable: the original
variables map to one and only one variable in the reduced data set.
'partition' is flexible, as well: how variables are selected to
reduce, how information loss is measured, and the way data is reduced
can all be customized. 'partition' is based on the Partition
framework discussed in Millstein et al. (2020)
