Dear R community
I'm new to R and I'd like to ask for hints how to approach the following
problem:
I have two vectors of count data 'observed_S' and 'observed_A'. Whereas
'observed_S' follows a neg. binomial distribution but 'observed_A' is a
mixture of an unknown variable 'A' (also from a neg. binomial
distribution) and a shadow of 'observed_S', so to say.
Therefore my model can be expressed by: observed_A = factor*observed_S + A
I d like to find the factor explaining my two data vector most
coherently. but I m overwhelmed by the different packages dealing with
neg. binomial distribution regression. Can someone please point me which
package is most useful for the above described purpose?
Thank you very much in advance
Regards
Fabian
