## 数学网课代修|概率统计代写Probability and Statistics代考|Basic Probability Models

This chapter will introduce the general notions of probability. Most of it will seem intuitive to you, and intuition is indeed crucial in the field of probability and statistics. On the other hand, do not rely on intuition alone; pay careful attention to the general principles which are developed. In more complex settings intuition may not be enough, or may even mislead you. The tools discussed here will be essential, and will be cited frequently throughout the book.

In this book, we will be discussing both “classical” probability examples involving coins, cards and dice, and also examples involving applications in the real world. The latter will involve diverse fields such as data mining, machine learning, computer networks, bioinformatics, document classification, medical fields and so on. Applied problems actually require a bit more work to fully absorb, but needless to say, you will derive the most benefit from those examples rather than ones involving coins, cards and dice. ${ }^{1}$

## 数学网课代修|概率统计代写Probability and Statistics代考|Bus Ridership

Consider the following analysis of bus ridership, which (in more complex form) could be used by the bus company/agency to plan the number of buses, frequency of stops and so on. Again, in order to keep things easy, it will be quite oversimplified, but the principles will be clear.
Here is the model:

• At each stop, each passsenger alights from the bus, independently of the actions of others, with probability $0.2$ each.
• Either 0,1 or 2 new passengers get on the bus, with probabilities $0.5$, $0.4$ and $0.1$, respectively. Passengers at successive stops act independently.
• Assume the bus is so large that it never becomes full, so the new passengers can always board.
• Suppose the bus is empty when it arrives at its first stop.
Here and throughout the book, it will be greatly helpful to first name the quantities or events involved. Let $L_{i}$ denote the number of passengers on the bus as it leaves its $i^{\text {th }}$ stop, $i=1,2,3, \ldots$ Let $B_{i}$ denote the number of new passengers who board the bus at the $i^{\text {th }}$ stop.

• 在每一站，每一位乘客从公共汽车上下来，独立于其他人的行动，有概率0.2每个。
• 0,1 或 2 名新乘客上车，概率0.5, 0.4和0.1， 分别。连续停靠的乘客独立行动。
• 假设公共汽车很大以至于它永远不会满员，所以新乘客总是可以上车。
• 假设公共汽车到达第一站时是空的。
在这里和整本书中，首先命名所涉及的数量或事件将非常有帮助。让大号一世表示巴士离开时的乘客人数一世th 停止，一世=1,2,3,…让乙一世表示在一世th 停止。

## MATLAB代写

MATLAB 是一种用于技术计算的高性能语言。它将计算、可视化和编程集成在一个易于使用的环境中，其中问题和解决方案以熟悉的数学符号表示。典型用途包括：数学和计算算法开发建模、仿真和原型制作数据分析、探索和可视化科学和工程图形应用程序开发，包括图形用户界面构建MATLAB 是一个交互式系统，其基本数据元素是一个不需要维度的数组。这使您可以解决许多技术计算问题，尤其是那些具有矩阵和向量公式的问题，而只需用 C 或 Fortran 等标量非交互式语言编写程序所需的时间的一小部分。MATLAB 名称代表矩阵实验室。MATLAB 最初的编写目的是提供对由 LINPACK 和 EISPACK 项目开发的矩阵软件的轻松访问，这两个项目共同代表了矩阵计算软件的最新技术。MATLAB 经过多年的发展，得到了许多用户的投入。在大学环境中，它是数学、工程和科学入门和高级课程的标准教学工具。在工业领域，MATLAB 是高效研究、开发和分析的首选工具。MATLAB 具有一系列称为工具箱的特定于应用程序的解决方案。对于大多数 MATLAB 用户来说非常重要，工具箱允许您学习应用专业技术。工具箱是 MATLAB 函数（M 文件）的综合集合，可扩展 MATLAB 环境以解决特定类别的问题。可用工具箱的领域包括信号处理、控制系统、神经网络、模糊逻辑、小波、仿真等。
