4. Let’s compare the results you calculated for Q3b with results from a multiple linear regression. 4a. Would additionally controlling for ‘depth’ and ‘latitude’ be helpful? In other words, is a model that includes ‘depth’, ‘latitude’ and ‘longitude’ superior in model fit to a model that includes only ‘longitude’? Output for a multiple linear regression which includes longitude, depth, and latitude is provided below. (2 points) 4b. Interpret the parameter estimate for ‘longitude’ from the multiple linear regression output. (1...

Suppose we conduct a study to determine the predictors of
mortality among adults in an intensive care unit (ICU). We collect
the vital status (STA) of 200 individuals; STA is coded as 0 if the
individual “Lived” and 1 if the individual “Died”. Data on
potential predictors were also collected including age (in years),
presence of cancer (CAN, coded as 0=No and 1=Yes), CPR prior to ICU
admission (CPR, coded as 0=No and 1=Yes), probable infection at ICU
