 JMLC can be configured to gather runtime statistics, as in the MLContext API, by calling Connection's `setStatistics()`
 method with a value of `true`. JMLC can also be configured to gather statistics on the memory used by matrices and
-frames in the DML script. To enable collection of memory statistics, call Connection's `gatherMemStats()` method
+frames in the DML script. To enable collection of memory statistics, call PreparedScript's `gatherMemStats()` method
 with a value of `true`. When finegrained statistics are enabled in `SystemML.conf`, JMLC will also report the variables
 in the DML script which used the most memory. An example showing how to enable statistics in JMLC is presented in the
 section below.
