response (dependent) variables - one particular variable that we are interested in understanding or modeling (y) predicting or explanatory (independent) variables - a set of other variables that might be useful in predicting or modeling the response variable (x1, x2) What kind of variable is a response variable and why? - random, because it varies with changes in the predictor/s along with other random changes. What kind of variable is a predicting variable and why? - fixed, because it ...

A Calibration procedure calls for checking a chemical cell oxygen analyzer daily. The range of the analyzer is 0 to 1000 PPM, and the procedure states that ambient air be used for the check. The chemical cell costs $350 and has a rated six months life. Cells are being replaced monthly.You Should: - A. Try to find a supplier of the sensor cells that is not as expensive. B. recommend a different type analyzer be used. C. recommend that a calibration system be installed using a 1000 PPM calibr...

ISYE6414 Final exam 2022>2023 update The prediction interval of one member of the population will always be larger than the confidence interval of the mean response for all members of the population when using the same predicting values.ANS****true See 1.7 Regression Line: Estimation & Prediction Examples "Just to wrap up the comparison, the confidence intervals under estimation are narrower than the prediction intervals becausethe prediction intervals have additional variance from t...

Logistic Regression correct answers Commonly used for modeling binary response data. The response variable is a binary variable, and thus, not normally distributed. In logistic regression, we model the probability of a success, not the response variable. In this model, we do not have an error term g-function correct answers We link the probability of success to the predicting variables using the g link function. The g function is the s-shape function that models the probability of success...
