Discrepancies with SEER Cancer Statistics Review (CSR)

I used the program on SEER data and do not get the same answers as in the SEER Cancer Statistics Review. Why?

Answer:

The SEER Cancer Statistics Review (CSR) uses the same Joinpoint Regression Program. Their analysis uses the "Input Standard Error of Response" setting for the Heteroscedastic Errors Option using the standard error of the rate as calculated by SEER*Stat. Using these options and the current default number of permutations (4499), if the Joinpoint Regression Program chooses the model with 0 joinpoints, the annual percentage rate change will agree with the calculation of this value given in the CSR.
