otlog  R Documentation 
Estimating the (single) parameter of the 1truncated logarithmic distribution.
otlog(lshape = "logitlink", gshape = ppoints(8), zero = NULL)
lshape, gshape, zero 
Same as

The 1truncated logarithmic distribution is a logarithmic distribution but with
the probability of a one being zero. The other probabilities are scaled
to add to unity.
