Apache Commons Math3 Exception: Insufficient Data for Predictors

This\ exception\ is\ thrown\ by\ the\ Apache\ Commons\ Math\ library\ when\ there\ is\ not\ enough\ data\ available\ for\ the\ given\ number\ of\ predictors\ in\ a\ mathematical\ operation.\ \n\ \nIn\ this\ specific\ case,\ the\ exception\ message\ states\ that\ there\ is\ only\ one\ row\ of\ data\ available,\ but\ there\ is\ a\ need\ for\ one\ predictor.\ This\ means\ that\ the\ operation\ being\ performed\ requires\ at\ least\ one\ more\ row\ of\ data\ to\ accurately\ predict\ or\ calculate\ the\ desired\ result.\ \n\ \nTo\ resolve\ this\ issue,\ you\ need\ to\ ensure\ that\ you\ have\ enough\ data\ points\ for\ the\ given\ number\ of\ predictors.\ You\ can\ either\ collect\ more\ data\ or\ adjust\ the\ number\ of\ predictors\ required\ for\ the\ operation\ to\ match\ the\ available\ data.
