Which of the following is/are true regarding logistic regression?

a. This technique is most often used to analyze data from large, prospective cohort studies.

b. Interpretation of the results for a variable included in a multivariate logistic regression model should always include the direction of the association, whether or not it is statically significant, and a statement that this is the observed relationship after controlling for the other factors in the model.

c. If the R2 value for a multivariate logistic regression model is 0.24, p = 0.001, we can accept the alternate hypothesis that that the set of independent variables included in the m

1. Explain why one would use a probability density function rather than a probability function to quantify the uncertainty of a specific measurand. 2. Explain the main difference between a normalized Gaussian function and a standard Gaussian function.In a single channel automatic car wash, cars arrive following Poisson distribution at the rate of 20 per hour. It takes an average of 2 minutes to wash a car, and the service time follows exponential distribution. Find the following operating characteristics of the system (10 marks). a) What is the probability that 4 cars arrive within 10 minutes? b) What is the probability that no car arrives within 5 minutes? c) What is the probability that a car is washed in less than 1.5 minutes.Which of the following statements is not correct?
