orgapachecommonsmath3exceptionMathIllegalArgumentException not enough data 1 rows for this many predictors 1 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.

In 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.

To 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
