R coxph baseline hazard
WebThe efficacy of immune checkpoint blockade (ICB) varies greatly among metastatic non-small cell lung cancer (NSCLC) patients. Loss of heterozygosity at the HLA-I locus (HLA-LOH) has been identified as an important immune escape mechanism. However, WebFix an oversight in aareg: when coxph and survreg were converted from using +cluster() in a formula to cluster as an argument, that same change needed to be made in aareg. Pointed out by zdgager. The std of the cumulative hazard is now present, for select cases of a coxph model curve. More work remains to be done to return the std for all cases.
