wlrm_untransformed.Rd
This function implements the untransformed version of the species richness estimation procedure outlined in Rocchetti, Bunge and Bohning (2011).
wlrm_untransformed( input_data, cutoff = NA, print = NULL, plot = NULL, answers = NULL )
input_data  An input type that can be processed by 

cutoff  Maximum frequency count to use 
Deprecated; only for backwards compatibility 

plot  Deprecated; only for backwards compatibility 
answers  Deprecated; only for backwards compatibility 
An object of class alpha_estimate
, or alpha_estimates
for phyloseq
objects
This estimator is based on the negative binomial model and for that reason generally produces poor fits to microbial data. The result is usually artificially low standard errors. Caution is advised.
