If the value of a variable at time t + 1 is partly determined by its value at time t, this is called:
A)collinearity.
B)time series.
C)autocorrelation.
D)covariance.

Question

Quizplus · Accepted Answer

Autocorrelation refers to the correlation between values of the same variable at different points in time. This suggests that the variable's value at time t affects its value at time t + 1, indicating a level of dependence between the two. Collinearity refers to the correlation between two or more variables, and covariance refers to the measure of how much two variables change together. Time series generally refers to the study of data collected over time.
