Hello,
I am trying to calculate the expected mean for progression free survival data for Gamma model, However, the following error keep resulting:
mean_gamma(shape = 1.497, scale=0.80*0.4268)
Error in mean_gamma(shape = 1.497, scale = 0.8 * 0.4268) : unused argument (scale = 0.8 * 0.4268)
cant understand what went wrong?
