: Which values for DMDEDUC2x and RIAGENDRx are represented in our intercept, or what is our reference level? View
: What type of model should we use when our target outcome, or dependent variable, is continuous? View
: Are the predictors for this model statistically significant, yes or no? (Hint: What are their p-values?) View
: Fill in the blanks. With 95% confidence, I estimate that the increase in log odds of smoking 100+ cigarettes for each increase by one in BMI, while holding Age constant, is between ____ and ____, on average. View
: We’d like to predict the log odds of smoking 100+ cigarettes for a given individual using the logistic regression model with the two variables: BMI and Age. For an individual with a BMI of 22 who is 45 years old, what would the predicted log odds be? View
: The sample of adults surveyed in NHANES contains adults age 20-80 with BMIs of 14.5-64.6. For the individual with a BMI of 22 who is 45 years old, do you trust the predicted log odds calculated above as being reasonable? View
: Two probabilities have been transformed using the logit function. The two values after transformation are -2 and 0.25. Which of the two values corresponds to a higher original probability? View
: Which of the following is a possible form/shape for a logistic regression model, where the y-axis represents the probability of success? View
: The 95% confidence interval for the coefficient for Age is given above as (0.014, 0.020). If instead we wanted a 90% confidence interval, how would the width of the interval change? View
: Based on the logistic regression with both Age and BMI as covariates, are the coefficients statistically significant at a two-sided 10% significance level? View
