在我的.bib文件中，有以下两个条目：

@book{si20,
    title = {Introduction to Econometrics with R},
    author = {Schmelzer, Martin Arnold, Alexander Gerber, and Martin, Christoph Hanck},
    url = {https://www.econometrics-with-r.org/},
    urldate = {2020-10-02},
    year = {2020}
}

@Article{pcalg,
    title = {Causal Inference Using Graphical Models with the {R}
      Package {pcalg}},
    author = {Markus Kalisch and Martin M\"achler and Diego Colombo and
      Marloes H. Maathuis and Peter B\"uhlmann},
    journal = {Journal of Statistical Software},
    year = {2012},
    volume = {47},
    number = {11},
    pages = {1--26},
    url = {https://www.jstatsoft.org/article/view/v047i11},
  }

我的文档如下所示：

\documentclass{article}
\usepackage[utf8]{inputenc}

\title{Test citations}
\author{Jaime Sevilla}
\date{November 2020}
\usepackage[
backend=biber, natbib,
style=numeric
]{biblatex}
\addbibresource{name.bib}

\begin{document}

\maketitle

\section{Introduction}

\cite{si20}

\cite{pcalg}

\printbibliography

\end{document}

乍一看，我认为两个bib条目的格式都正确。但只有第二个有效！

发生了什么事？我该如何修复第一个bib条目？

看起来si20条目中的作者字段缺少一些用于分隔作者的“and”。正确的格式si20应如下所示：

@book{si20,
    title = {Introduction to Econometrics with R},
    author = {Hanck, Christoph and Arnold, Martin and Gerber, Alexander and Schmelzer, Martin},
    url = {https://www.econometrics-with-r.org/},
    urldate = {2020-10-02},
    year = {2020}
}
