I'm sorry. I just saw the post of Baltas and your answer.
Kind regards

Dear Mr. Komarov,

I am just searching the Internet for an application to compute the HAC-Standard Error of Newey and West (1987) that I want to use to calculate an unbiased t-statistic of a sample I created.
The sample contents Buy-and-Hold excess returns of Firms over periods larger then 2 years. With a limited data sample you will only have enough observations when the Formation- and Holding periods are overlapping.
The question is now how I can extract the HAC standard error from your script regstats2.m to calculate the t-statistic with a robust standard error or especially if that’s possible.

I tried to write a PN but that didn't work. (Unknown e-mail address)

Thanks for the Help!
Sven
