Consider independent observations y₁, ..., yn from the model Y; ~ Poisson(u). Using likelihood L(u) and log-likelihood 1(μ) as appropriate, compute thefollowing items.1. Derive the maximum likelihood estimate .2. Write the second derivative of log-likelihood 1(u).3. Give an expression of the approximated asymptotic standard error of û by plugging in the estimate . To this end, estimate the Fisher Information Matrixby ý = − 3 -/-1(μ) |µ=û and then s. e. (μ)(û) =4. Consider data 23, 14, 16, 22, 18, 22, 24, 30. Using your formulæ, compute and write numerical estimates û, s. e. (û) and give a 95% confidence interval forμ using the normal approximation.= √√₁²¹VEI

The US government is interested in understanding what predicts death rates. They have a set of data that includes the number of deaths in each state, the number of deaths resulting from vehicle accidents (VEHICLE), the number of people dying from diabetes (DIABETES), the number of deaths related to the flu (FLU) and the number of homicide deaths (HOMICIDE). Your run a regression to predict deaths and get the following output: At α = .10, which variable(s) is/are significant predictors of deaths?

For 50 randomly selected speed dates, attractiveness ratings by males of their female date partners (x) are recorded along with the attractiveness ratings by females of their male date partners (y); the ratings range from 1 to 10. The 50 paired ratings yield *= 6.4. y = 6.0, r= - 0.279, P-value = 0.050, and g = 8.27 - 0.357x. Find the best predicted value of y (attractiveness rating by female of male) for a date in which the attractiveness rating by the male of the female is x=7. Use a 0.10 significance level. The best predicted value of y when x = 7 is (Round to one decimal place as needed.)

When we fit a logistic regression model with a single explanatory term, x, we often assume that logit (pi) Bo + ₁x₂ where, for the ith observation, p; is the probability of a trial being successful and *; is the value of the explanatory variable. Which of the following is a good reason for using the logit link function? We can't use more than one explanatory term unless we use this link function. It allows us to model nonconstant variance in the response variable. It ensures that the probability of success is between 0 and 1. It ensures that the variance of the response is the same for all observations.
