I need to configure my bibtex file to match Elsevier's reference requirement (look for number 10). For example:
For periodicals
Griffiths, W. and G. Judge, 1992, Testing and estimating location vectors when the error covariance matrix is unknown. Journal of Econometrics 54, 121-138.
My current bibtex file looks like this:
@ARTICLE{Adrian2008,
AUTHOR = {Adrian, T., Rosenberg, J.,},
TITLE = {Stock Returns and Volatility: Pricing the Short-Run and Long-Run Components of Market Risk},
JOURNAL = {Journal of Finance},
YEAR = {2008},
volume = {63},
pages = {2997-3030}
}
And inside my main document, I refer to my bibtex file as:
\begingroup
\let\itshape\upshape %I use this to remove the italics.
\bibliographystyle{plain}
\bibliography{lit3}
\endgroup
Following my example above, it generates this reference format:
T. Adrian and J. Rosenberg. Stock returns and volatility: Pricing the short-run and long-run components of market risk. Journal of Finance, 63:2997–3030, 2008.
How can I make the changes to my bibtex file in order to match Elsevier's requirements?
