Time Series algorithm problem

    Question

  • Hi,

    problem-In Time Series Algorithm predication  is wrong if Sales value is negative

    i  have data for more than  3 years  ,

    sample data like

    Year/Month Zone-1 Sales
    201001 -5467.66
    201002 2345.88
    201003 -7895.33
    201004 2345.65
    201005 120.2333

    Due to negative value my prediction for next month is wrong. Please tell me how I can handle this problem. Negative values come due to sales return in zone.
