Thirty shipments by TransAtlantic Express designed to predict the likelihood a shipment would reach its port of destination on time yields the following information:

a. What is the likelihood a 500-ton shipment destined for a port 2,000 miles away will reach port on time?

b. Given the results seen here, calculate and interpret the −2 loglikelihood for the restricted model.

Estimation terminated at iteration number 5 because parameter estimates changed by less than .001.

c. Complete the classification table. Twelve of the 30 shipments did not arrive in a timely manner (were encoded as a “0”). Comment on its findings.
