Question about zero.truncated
Simulate a random sample of size n = 100 from the zero-truncated distribution
when = 2. [Note that you can do this by simulating data from the (un-truncated)
Poisson distribution and discarding the zeros.]
i. Provide R code which returns the value of the log-likelihood for a given data
vector, x, and parameter value, .
ii. Provide R code which returns the maximum likelihood estimate of for a given
data vector.
iii. Provide a single plot which shows:
---the log-likelihood in the range 1<=lambda<= 5, if we assume the data comes
from the Poisson distribution;
---the log-likelihood in the range 1<=lambda<= 5, if we assume the data comes
from the zero-truncated Poisson distribution;
---the maximum likelihood estimate for for both the Poisson distribution and
the zero-truncated Poisson distribution.
iv. Derive an expression for the dierence between the two log-likelihood functions,
and hence comment on your plot in (iii). Comment on how well each of the
MLEs estimates the true value of
Thank you for everybody,
