The most common method of test autocorrelation is the Durbin-Watson test. Without getting too technical, the Durbin-Watson is a statistic that detects autocorrelation from aregression analysis. The Durbin-Watson always produces a test number range from 0 to 4. Values closer to 0 indicate a great...
Statistic vs. Parameter.A parameter is data about an entire population. For example, if you want to find out which classes freshmen at a certain college were taking, you could ask everyone (perhaps via email) and it would be possible to get a parameter. Statistics are when you base your ...

Ramsey and Rothman (1996) also introduced a new procedure to test TR that became a standard approach to investigating business cycle properties such as asymmetry. It amounts to a TR test statistic distributed as a standard normal distribution: 𝑇−−√[𝛾̂2,1−𝛾2,1]𝑉𝑎𝑟...
