Answer :
Answer:
Option(b) is the correct answer to the given question
Step-by-step explanation:
1) If [tex]d\leq dl[/tex] then , there must be a positive Autocorrelation
According to it if the ratio d of durbin-watson is equal to or less than dL then it is called as Positive Autocorrelation.
2 ) if , then it is Inconclusive
According to it If the coefficient d of the Durbin-Watson is between dL & du then it is called as Inconclusive.
3) if [tex]d\geq du[/tex] then there is No proof of the Autocorrelation
According to it if the d of the durbin-watson will be less than or equivalent to du then it is called as No Autocorrelation.
4) If [tex]d \leq (4-du)[/tex] ) then there is No proof of the Autocorrelation
According to it if the d of the durbin-watson will be less than or equivalent to 4- du then it is called as No Autocorrelation.
5) If the [tex]( 4 - du ) \leq d \leq ( 4 -dl )[/tex] , then it is Inconclusive
According to it if the d of the durbin-watson is between the [tex](4-du) \ and \ (4-dl)[/tex] then it is called as Inconclusive.
6) If the [tex]d \geq (4-dl)[/tex] then it called as negative Autocorrelation
According to it if the d of the durbin-watson is greater then [tex]4-dl[/tex] then it is called as negative autocorrelation.
- From the point 6 we can say that the option(B) is correct
- All the others options are not correct for (4 − dL), so these are incorrect option .
