[Tex/LaTex] Bibliography style does not change (Elsevier)

bibliographiesbibtex

I need to put the bibliography style in my paper like below:

Li, X., Heckman, N. E.(2003). Local linear extrapolation. Journal of Nonparametric Statistics 15, 565–578.

(so called author-year style, year in the parentheses and so forth)-

So I found a file for this style and put it in the style folder of Endnote.
And read my references again and export to Mendeley by XML file.
In Mendeley I also choose that style and export as .bib file.
Until now, those two programs show the result I want to have.

But it does not change style according to that style in LaTeX.

My LaTeX code is:

\documentclass[authoryear]{elsarticle}
\begin{document}

 ..........as \citep{Li2003}. .................

\bibliographystyle{elsarticle-harv}
\bibliography{n8}
\end{document}

But this only gives:

Li, X., Heckman, N. E., 2003. Local linear extrapolation. Journal of Nonparametric Statistics 15 (4-5), 565–578.

The year is not in parentheses and other parts are different.

This is a right '.bst' file for this journal. http://www.ctan.org/tex-archive/biblio/bibtex/contrib/newapa

I hope this helps other researchers having the same problem or likely having that problem.

Also, I think this file can apply to other journals of Elsevier.
