regression line (its predicted value).

51.

multiplicative

6. are always numeric and indicate either how

much or how many.

52.

focus group

7. a forecasting method for a wide variety of

time series data, for constant processes,

processes with linear trends, and for sea-

sonal data.

53.

Euclidean

8. calculated for each correlation is a primary

distance

source of information about the reliability

of the correlation.

54.

the significance

9. those that are manipulated.

level

55.

parsimonious

10. is the most commonly chosen type of dis-

model

tance, it is the geometric distance in the

multidimensional space.

56.

independent

11. represents a general systematic linear or

variables

nonlinear component that changes over

time and does not repeat or at least does not

repeat within the time range captured by

our data.

57.

time series data

12. a procedure when the line is computed so

that the squared deviations of the observed

points from that line are minimized.

58.

correlation

13. is used to increase or decrease the progres-

sive weight that is placed on dimensions on

which the respective objects are very differ-

ent.

59.

power distance

14. is a measure of the relations between two or

more variables.

60.

correlation

15. means that it has the fewest parameters and

coefficient R

greatest number of degrees of freedom

among all models that fit the data.
