62.Which of the following is not an assumption of logistic regression?

a.Linearity

b.Independence of errors

c.Multicollinearity

None of the above

62a.What does the log-likelihood measure?

a.The number of degrees of freedom in relation to the parameter set for the model

b.The way in which observed and predicted values fit the model of regression

c.The value of the correlation coefficient R and its corresponding R² value

d.None of the above

62b.What does the following graph illustrate? (PD stands for peritoneal dialysis.)

a.The higher the probability of technique failure, the more days needed to initiate PD.

b.The minimum time since initiation of PD, the higher the probability of technique failure.

c.The longer the time since initiation of PD, the higher the probability of technique failure.

d.None of the above.

62c.In determining the odds that a specific type of antibiotic preparation will cure otitis media in children, the odds ratio value was calculated to be greater than 1. With increases in the predictor, what will this mean for the outcome of the result?

a.A greater chance of a cure being achieved than if not treated.

b.A lesser chance of a cure being achieved.

c.A lesser chance of treatment being effective.

d.None of the above.
