5.15 According to the Independent newspaper (London, March 8, 1994), the Metropolitan Police in London reported 30,475 people as missing in the year ending March 1993. For those of age 13 or less, 33 of 3271 missing males and 38 of 2486 missing females were still missing a year later. For ages 14-18, the values were 63 of 7256 males and 108 of 8877 females; for ages 19 and above, the values were 157 of 5065 males and 159 of 3520 females. Analyze these data, including checking model fit and interpreting parameter estimates. (Thanks to Dr. P. M. E. Altham for showing me these data.) 2. Do Problem 5.15 on page 167 of Agresti.
