non normal distribution

Postby rahma » Mon May 06, 2013 4:12 am

Hello :)

The temporal serie is not normal distributed, even when i enter the Log

What solution do you suggest to me?

What exactly is the problem with the series being non-normal ?

The series being normal is not of any relevance for cointegration tests. Normality of series is almost never important. Normality of errors sometimes matters, but not often.

Hi,

Is non normal distribution in cross sectional data a problem?

If it is still existent even after logging data, what can be done?

Thank you

Non-normality of data is rarely a problem in large samples unless the departure from normality is extreme.
