generateCSV

public String generateCSV(int numOfLines,
                          String targetLabel,
                          double targetInitialValue,
                          double valueVolatility,

                          boolean withId)

Parameters:

numOfLines - Number of lines to generate as a dummy data set

targetLabel - Target to predict

targetInitialValue - The initial value that will be used for multiplication when calculating the target.

valueVolatility - A random value to be added to the computed value. computed by "volatility * Math.random () * targetInitialValue"

withHeader - true:generate csv with header row.

withId - true:generate autogenerated sequential id column

Returns:
