egammaAltCensored() produces errors

1

I have this data. It works with `elnormAltCensored()` but produces an error with `egammaAltCensored()`. ``` # test values vals

I provide a reprex for this as the object doesn't seem to be able to be written out properly, but when the AIC values are negative, then `plot()` doesn't work...
