Hi all, I am trying to fit a burr distribution to my log transformed tpm values and have filtered these values to be above 0. Other distributions such as weibull, pareto runs fine but i have encountered the below error when trying burr.

Error in manageparam(start.arg = start, fix.arg = fix.arg, obs = data, : Error in start.arg.default(obs, distname) : Unknown starting values for distribution burr.

I have used just burr_tpm <- fitdist(all_positives, "burr")

Any help is greatly appreciated, thank you!
