Hi, Kaplan states the hypothesis for a positive serial correlation test as H0 : no positive serial correlation Ha: positive serial correlation Table provides critical values and you make your decision My question is: How do you test for negative serial correlation as there is only one critical value table? Thanks. A
For negative correlation you have to check whether your DW statistic falls within the range (4-dl) and (4). Click the image for more on the topic.
That’s a very cool picture.
Where’d you get it?
Given the question was specific I thought it was more engaging to relate to the diagram rather than suggesting a link to the full article. I made sure to add hyperlink to the source though.
P.S. Why don’t you add commenting facilities in your website (such as Disqus) to encourage feedback? Also I am sure many people would gladly contribute towards the site usage and maintenance.
Great idea! I’ll look into it.
I’m setting up a subscription service. I want to test it on a ghost site for a while to make sure it doesn’t foul up anything else, then I’ll make it live.
How much you will charge for subscription and what will be included? Do you intend prepare premium subscription with live support?
None of that’s decided yet.
First things first: make sure it works properly.
One picture explains it all. Cheers.
