How to add year in my numeric citation style?

Question

\documentclass{article}
\usepackage[
backend=bibtex,
bibstyle=numeric,
citestyle=numeric,
natbib=true
]{biblatex}
\bibliography{biblio}

\begin{document}
\citet{federico2014reserve}
\printbibliography
\end{document}

The .bib file is omitted here. And this will give:

Federico, Vegh, and Vuletin [1].

I want a 'Author-year-number' style of citation like this:

Federico, Vegh, and Vuletin 2014 [1].

Is there a way to do so in biblatex? Thanks.

\textcite{<key>}, but usually you don't mix Harvard and Vancouver. — Johannes_B, May 01 '16 at 16:35
@Bernard: 'citestyle=authoryear' will drop the number index. — Alex Shen, May 01 '16 at 21:55
It doesn't make much sense, but see Is there a package that allows a citation style of Author, year number? and BibLaTeX citing style — moewe, May 02 '16 at 05:49
@moewe Thanks, I see the point. I want this way because I like the numeric citation while most people like the authoryear, so maybe this is a middle way... — Alex Shen, May 03 '16 at 19:15
I think what is liked by most people depends on what field you are in, in mathematics and the sciences a numeric style is very prevalent, while in the humanities I tend to see author-year styles or similar. — moewe, May 04 '16 at 04:49

A style like this doesn't make much sense to me. You give up the one big advantage of a numeric style: unintrusiveness. Since you add the author and year the citation gets longer, and the numeric label doesn't add any further information that the author-year part can't give you (if done properly, of course).

That said, you can just add the name and year to the cite macro, but then we also need to move about the brackets.

\renewcommand*{\nameyeardelim}{\addspace}

\DeclareCiteCommand{\cite}
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \usebibmacro{cite}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

\renewbibmacro*{cite}{%
  \printtext[bibhyperref]{%
    \printnames{labelname}%
    \setunit{\nameyeardelim}%
    \printfield{year}%
    \setunit{\addspace}%
    \printtext[labelnumberwidth]{%
      \printfield{prefixnumber}%
      \printfield{labelnumber}}%
    \ifbool{bbx:subentry}
      {\printfield{entrysetcount}}
      {}}}

Note that this redefines the \cite command and not \textcite/\citet.

In total

\documentclass{article}
\usepackage[
backend=bibtex,
style=numeric,
natbib=true
]{biblatex}
\bibliography{biblatex-examples}

\renewcommand*{\nameyeardelim}{\addspace}

\DeclareCiteCommand{\cite}
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \usebibmacro{cite}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

\renewbibmacro*{cite}{%
  \printtext[bibhyperref]{%
    \printnames{labelname}%
    \setunit{\nameyeardelim}%
    \printfield{year}%
    \setunit{\addspace}%
    \printtext[labelnumberwidth]{%
      \printfield{prefixnumber}%
      \printfield{labelnumber}}%
    \ifbool{bbx:subentry}
      {\printfield{entrysetcount}}
      {}}}

\begin{document}
\cite{sigfridsson}
\printbibliography
\end{document}

Thank you very much. I see the point and I agree it is strange. — Alex Shen, May 03 '16 at 19:20
