\nThe title kind of says it PROC QUANTLIFE new procedure in SAS 9.3
\nWhy DO we need a new procedure for survival analysis?<\/p>\n
======
\nSurvival analysis used to analyze time-to-event data
\nalready had procs lifetes, lifereg & phreg
\n========
\nLifereg is fine if you have IID errors – but what I’d you don’t . Enter quantile regression, possibly wearing a cape #Sasgf13 #noCape
\n=========
\nQy(tau) is the tau-th quantile of a random variable Y eg Qy(25) is 25th percentile
\n==========
\nQuantile regression – can have same slope & different intercept for each value given for tau
\nQuantile regression, option 2 can have different slopes for each value of tau #Sasgf13
\n=============<\/p>\n
Cumulative distribution function is the inverse of the quantile function #Sasgf13<\/p>\n
QUANTLIFE example shows covariate that has negative effect for those with short life but positive effect for those with longer life #Sasgf13<\/p>\n
Interested in survival analysis when covariates have non-linear relationship to time to event? Check the QUANTLIFE procedure paper #Sasgf13<\/p>\n","protected":false},"excerpt":{"rendered":"
