Match the following

List - IList - II
a. Unit Root Test1. Durbin-Watson Test
b. Contingency Table2. Student's t-test
c. Regression Coefficient3. Stationarity
d. Autocorrelation4. \(\chi^{2}\)-test

Codes : a b c d

  • A.2 3 1 4
  • B.4 2 3 1
  • C.3 4 2 1
  • D.3 2 1 4

Answer: C

The pairs are the unit root test with stationarity, the contingency table with the chi-square test, the regression coefficient with the Student's t-test, and autocorrelation with the Durbin-Watson test. This is a-3, b-4, c-2 and d-1.

A unit root test checks whether a series is stationary, a contingency table is tested with chi-square for association, a regression coefficient is tested with the t-test, and the Durbin-Watson statistic tests for serial correlation. The other codes pair the Durbin-Watson test with the unit root test.
