## 统计代写|时间序列分析代写Time-Series Analysis代考|Getting Started with Time Series Analysis

When embarking on a journey to learn coding in Python, you will often find yourself following instructions to install packages and import libraries, followed by a flow of a code-along stream. Yet an often-neglected part of any data analysis or data science process is ensure that the right development environment is in place. Therefore, it is critical to have the proper foundation from the beginning to avoid any future hassles, such as an overcluttered implementation or package conflicts and dependency crisis. Having the right environment setup will serve you in the long run when you complete your project, ensuring you are ready to package your deliverable in a reproducible and production-ready manner.

Such a topic may not be as fun and may feel administratively heavy as opposed to diving into the core topic or the project at hand. But it is this foundation that differentiates a seasoned developer from the pack. Like any project, whether it is a machine learning project, a data visualization project, or a data integration project, it all starts with planning and ensuring all the required pieces are in place before you even begin with the core development.

In this chapter, you will learn how to set up a Python virtual environment, and we will introduce you to two common approaches for doing so. These steps will cover commonly used environment management and package management tools. This chapter is designed to be hands-on so that you avoid too much jargon and can dive into creating your virtual environments in an iterative and fun way.
As we progress throughout this book, there will be several new Python libraries that you will need to install specific to time series analysis, time series visualization, machine learning, and deep learning on time series data. It is advised that you don’t skip this chapter, regardless of the temptation to do so, as it will help you establish the proper foundation for any code development that follows. By the end of this chapter, you will have mastered the necessary skills to create and manage your Python virtual environments using either conda or venv.

As we dive into the various recipes provided in this book, you will be creating different Python virtual environments to install all your dependencies without impacting other Python projects.

You can think of a virtual environment as isolated buckets or folders, each with a Python interpreter and associated libraries. The following diagram illustrates the concept behind isolated, self-contained virtual environments, each with a different Python interpreter and different versions of packages and libraries installed:

These environments are typically stored and contained in separate folders inside the envs subfolder within the main Anaconda folder installation. For example, on macOS, you can find the envs folder under Users//opt/anaconda3/ envs/. On Windows OS, it may look more like C: $\backslash$ Users $\backslash<$ yourusername $>\backslash$ anaconda3 \envs.
Each environment (folder) contains a Python interpreter, as specified during the creation of the environment, such as a Python $2.7 .18$ or Python $3.9$ interpreter.
Generally speaking, upgrading your Python version or packages can lead to many undesired side effects if testing is not part of your strategy. A common practice is to replicate your current Python environment to perform the desired upgrades for testing purposes before deciding whether to move forward with the upgrades. This is the value that environment managers (conda or venv) and package managers (conda or pip) bring to your development and production deployment process.

## 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。
