TABLE 15-5
What are the factors that determine the acceleration time (in sec.)from 0 to 60 miles per hour of a car? Data on the following variables for 171 different vehicle models were collected:
Accel Time: Acceleration time in sec.
Cargo Vol: Cargo volume in cu.ft.
HP: Horsepower
MPG: Miles per gallon
SUV: 1 if the vehicle model is an SUV with Coupe as the base when SUV and Sedan are both 0
Sedan: 1 if the vehicle model is a sedan with Coupe as the base when SUV and Sedan are both 0
The coefficient of multiple determination ( )for the regression model using each of the 5 variables Xj as the dependent variable and all other X variables as independent variables are,respectively,0.7461,0.5676,0.6764,0.8582,0.6632.
-True or False: Referring to Table 15-5,there is reason to suspect collinearity between some pairs of predictors based on the values of the variance inflationary factor.
Opposite State
Refers to a condition or value that is directly in contrast or opposition to another.
Expression
An instruction that combines values and operators and always produces another value.
Right To Left Associativity
The order in which operators of the same precedence level are evaluated, from right to left, in some programming languages.
Conditional Statement
A programming statement that executes a block of code based on whether a specified condition evaluates to true or false.
