 \section{ElegantBook 更新说明}
-在这几年间，我们收到了很多用户的反馈，主要的问题涉及到字体安装，编码支持，定理浮动，定理跨页，交叉引用等等。我们思前想后，原先让用户安装字体以追求视觉上的美观并不完美，用户陷入了巨大的麻烦，这违背了我们的模板初衷。因此我们在新版中删除了这部分，用户无需安装任何字体。让我们来看下此次 ElegantBook 模板 3.x 更新的主要内容有：

 \section{编译方式}
 
 本模板基于基础的 book 文类，所以 book 的选项对于本模板也是有效的。默认编码为 UTF-8，推荐使用 \TeX{} Live 编译。本文编写环境为 Win10 (64bit) + \TeX{} Live 2018，支持 \lstinline{PDFLaTeX} 以及 \lstinline{XeLaTeX} 编译。
-\subsection[选择 PDFLaTeX 编译]{选择 \lstinline{PDFLaTeX} 编译}
-如果你使用 \lstinline{PDFLaTeX} 编译，默认的 Computer Modern 字体被换成了 \lstinline{newtx} 系列字体，默认的字体字号是 12 pt。关于字体设置的宏包主要用到了：
-\begin{itemize}
-   \item \lstinline{newtxtext} 用于文档正文字体，类似于 Times New Roman 字体。
-   \item \lstinline{newtxmath} 用于数学字体，搭配 \lstinline{newtxtext} 非常合适。
-   \item \lstinline{FiraMono} 用于打字机字体，并使用了 \lstinline{scale=0.7} 选项。
-   \item \lstinline{ctex} 用于中文字体设置，并使用了 \lstinline{scheme=plain} 选项。
-\end{itemize}
-一次完整的编译：\lstinline[breaklines]{PDFLaTeX -> BibTeX -> PDFLaTeX*2}。
-
-\subsection[选择 XeLaTeX 编译]{选择 \lstinline{XeLaTeX} 编译}
-如果你选择 \lstinline{XeLaTeX} 编译的话，那么设置字体的宏包为 \lstinline{fontspec} 和 \lstinline{xeCJK}。由于模板中使用的字体是 Windows 中的字体，所以如果你使用其他操作系统，比如 Linux 或者 Mac OS，那么你需要把所用字体替换为你系统中的字体。设置字体的命令：
-
-\begin{lstlisting}[frame=single]
-\RequirePackage{fontenc}
-\RequirePackage[no-math]{fontspec}
-\setmainfont{Times New Roman}[NFSSFamily=ntxtlf]
-\setsansfont{Arial}
-%\setmonofont[Scale=0.7]{Courier New}
-\RequirePackage{xeCJK}
-\RequirePackage{xunicode}
-\setCJKmainfont[BoldFont={SimHei},ItalicFont={KaiTi}]{SimSun}
-\setCJKsansfont[BoldFont={SimHei},ItalicFont={KaiTi}]{KaiTi}
-\setCJKmonofont[BoldFont={SimHei},ItalicFont={KaiTi},Scale=0.7]{Microsoft YaHei}
-\XeTeXlinebreaklocale "zh"
-\XeTeXlinebreakskip = 0pt plus 1pt minus 0.1pt
-\RequirePackage{newtxmath}
-\end{lstlisting}
-一次完整的编译：\lstinline[breaklines]{XeLaTeX -> BibTeX -> XeLaTeX*2}。
 
 
 \section{语言模式}
 本模板内含两套语言环境，改变语言环境会改变图表标题的引导词（图，表），文章结构词（比如目录，参考文献等），以及定理环境中的引导词（比如定理，引理等）。不同语言模式的启用如下：

 \begin{remark}
-不管选用中文环境（\lstinline{lang=cn}）还是英文环境（\lstinline{lang=en}）均可输入中文。另外如果在笔记中使用了抄录环境（\lstinline{lstlisting}），并且其中包括了中文，请务必使用 \lstinline{XeLaTeX} 编译。

 我们知道最小二乘法可以用来处理一组数据，可以从一组测定的数据中寻求变量之间的依赖关系，这种函数关系称为经验公式。本课题将介绍最小二乘法的精确定义及如何寻求点与点之间近似成线性关系时的经验公式。假定实验测得变量之间的 $n$ 个数据，则在平面上，可以得到 $n$ 个点，这种图形称为 “散点图”，从图中可以粗略看出这些点大致散落在某直线近旁, 我们认为其近似为一线性函数，下面介绍求解步骤。

 \chapter{Elegant\LaTeX{} Templates}
 
 On the occasion of this release, we, Elegant\LaTeX{} Program, want to reintroduce our work to you. We are committed to creating a series of beautiful, elegant, easy to use \LaTeX{} templates for users. The Elegant\LaTeX{} is currently composed of \href{https://github.com/ElegantLaTeX/ElegantNote}{ElegantNote}, \href{https://github.com/ElegantLaTeX/ElegantBook}{ElegantBook}, \href{https://github.com/ElegantLaTeX/ElegantPaper}{ElegantPaper} for typesetting notes, books, and working papers respectively. 
 
-The latest version is available on \href{https://github.com/ElegantLaTeX/ElegantBook/releases}{Github:ElegantBook/releases}. This guide describes some settings of this template and how to use it. If you have any other questions, suggestions or comments, please feel free to contact us.

 \section{ElegantBook Updates}
-Over these years, we've received a lot of feedback from users, with major issues related to font installation, coding support, theorem class environments floats, theorem cross-page, cross-references, and etc. We really think about these problems, it wasn't elegant to let the user install the font for visual beauty since users got into a lot of trouble, which went against the concept of our template. So we've removed that from the new version, users don't have to install any fonts. Let's take a look at the ElegantBook template 3.x updates:

This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Peer-to-peer (P2P) lending, as a novel economic lending model, has triggered new challenges on making effective investment decisions. In a P2P lending platform, one lender can invest N loans and a loan may be accepted by M investors, thus forming a bipartite graph. Basing on the bipartite graph model, we built an iteration computation model to evaluate the unknown loans. To validate the proposed model, we perform extensive experiments on real-world data from the largest American P2P lending marketplace - Prosper. By comparing our experimental results with those obtained by Bayes and Logistic Regression, we show that our computation model can help borrowers select good loans and help lenders make good investment decisions. Experimental results also show that the Logistic classification model is a good complement to our iterative computation model, which motivates us to integrate the two classification models. The experimental results of the hybrid classification model demonstrate that the logistic classification model and our iteration computation model are complementary to each other. We conclude that the hybrid model (i.e., the integration of iterative computation model and Logistic classification model) is more efficient and stable than the individual model alone.},

A signal (e.g., age) partitions consumers into subsets (e.g., young and old). A regulator restricts price-discrimination on the basis of the signal if the consumer subsets where the level of cost is higher are also the subsets where there is greater deadweight loss due to adverse selection. Such signals are empirically common. To illustrate the welfare benefit of price discrimination policy, I use a structural model to estimate its impact on the UK annuities market. The model is estimated using proprietary data that include the annuity seller's estimate of each individual's longevity. I find that restricting price discrimination can increase consumer surplus by the equivalent of about {\pounds}6.5 million per year.},

-abstract = {We use data from a major peer-to-peer lending marketplace in China to study whether female and male investors evaluate loan performance differently. Controlling for variables of investor demographics, investor experience, and loan characteristics, we find that loans invested by female investors are more likely to default and have lower loan return in the future than loans invested by male investors. We define abnormal default or abnormal loan return as the part of the loan default or the part of loan return that is not explained by loan characteristics and find that the loans invested by female investors have higher abnormal default and lower abnormal loan return than the loans invested by male investors. Furthermore, female investors perform similarly to male investors in abnormal default or abnormal loan return when investors have high levels of education or income or when investors work in finance or information technology industries.},

-abstract = {The objective of our paper is to explore the role of P2P lending platforms through the prism of the theory of financial intermediation. P2P lending platforms perform the brokerage function of financial intermediaries by matching lenders' supply and borrowers' demand of funding, according to the risk and the maturity of their needs. Unlike banks, P2P lending platforms do not create money and do not perform risk and maturity transformation. However, they can organize secondary markets to trade loan contracts before maturity and some P2P lending platforms aim at providing a fixed income to lenders. To ensure efficient and sustainable financial intermediation, P2P lending platforms need to ensure that they are not subject to principal-agent problems and that their incentives coincide with those of lenders. The possibility of orderly resolution of P2P lending platforms failures might decrease moral hazard problems that are inherent in the modern financial intermediation.},
