- If there are too few data columns in the input data file.
Error Message: Too few data columns in Input Data File.
Reason(s) triggered: This is triggered when the variable positions set in the session go beyond the number of variables found in any given data line from the input data file. Most likely the input data file (or data file name) was changed and now it does not match up with what was used to set up the original session.
- If Joinpoint is computing age-adjusted rates and encounters a by-group with a different number of observations from the previous by-group.
Error Message: You cannot calculate age-adjusted rates from a data file with differing number of observations per cohort!
- If the shift-value specified by the user is greater than the largest interval between independent variable values.
Error Message: Error with shift value: The shift value cannot be larger than the largest independent variable interval.
- If the Independent variable has a format and Joinpoint encounters a value that is NOT in the format.
Error Message: "???" is not a valid value for the independent variable.
- If the independent variable has a value that is non-numeric.
Error Message: Error in Data File: Joinpoint cannot process by-groups where independent variable values are non-numeric.
- If two or more independent variable values are found to be equal (within a given cohort).
Error Message: Error in Data File: Joinpoint cannot process by-groups where two or more independent variable values are equal.
- For comparison runs, if the inner-most by variable has only one grouping.
Error Message: You cannot test for pair-wise differences when the inner-most by variable only has one category.
- When age-adjusted rates are computed, if the standard population value used to compute an age-adjusted rate is zero.
Error Message: Standard Population denominator is zero.
- If there are one or more cohorts that do not have enough data points for the specified job parameters. The following formula is used to determine the minimum number of required data points for any given cohort:
Min Required Observations = (2 * Min Number of Observations from a Joinpoint to either end of data) + ((Max Joinpoint - 1)*(min num of observations between two joinpoints)) + Max Joinpoint;
Error Message: Too few observations to fit specified model. Please verify that your data is sorted correctly.
