Hello,
I am trying to input a generalized gamma curve into excel. We have curve parameters from SAS (shape, scale, and intercept), but are having trouble figuring out how to use them in the formula given for the survival function G'(v) on the SAS website http://support.sas.com/documentatio...default/viewer.htm#statug_lifereg_sect019.htm
We’re unsure of what δ refers to in the SAS outputs. We initially thought it would refer to the ‘shape’ parameter, but that doesn’t seem to work. For the incomplete gamma function, we have been using the GAMMA.DIST function, and for the complete gamma function, we’ve been using EXP(GAMMALN.
This is very urgent
, so I would appreciate any helps as soon as possible. Thank you very much in advance!!
