`fit` |
Object of class "joinpoint". |

`type` |
Type of trend summary measure. Supported measures are: HAZ_APC(HR) - annual percentage changes of hazard, HAZ_APC(CS) - annual percentage changes of cumulative relative surviva, HAZ_AC(CS) - annual changes of cumulative relative survival. The default is HAZ_AC(CS). |

`interval` |
Years after diagnosis. Only needed for HAZ_APC(CS) and HAZ_AC(CS). |

The estimates and standard erros of the trend summary measure.

data(prostate);
# Fit the survival join point model with zero join points, i.e., fit the proportional hazard relative survival model.
fit1 = joinpoint(~Year, data=prostate, numJPoints = 0);
# Get the estimates and standard errors of the annual changes of cumulative relative survival.
haz_ac = aapc(fit1, type="HAZ_AC(CS)", interval=5);
