统计代写|Matplotlib代写|Quantitative and Qualitative Data Analysis

Data analysis is completely focused on data. Depending on the nature of the data, it is possible to make some distinctions.
When the analyzed data have a strictly numerical or categorical structure, then you are talking about quantitative analysis, but when you are dealing with values that are expressed through descriptions in natural language, then you are talking about qualitative analysis.

Precisely because of the different nature of the data processed by the two types of analyses, you can observe some differences between them.
Quantitative analysis has to do with data with a logical order or that can be categorized in some way. This leads to the formation of structures within the data. The order, categorization, and structures in turn provide more information and allow further processing of the data in a more mathematical way. This leads to the generation of models that provide quantitative predictions, thus allowing the data analyst to draw more objective conclusions.
Qualitative analysis instead has to do with data that generally do not have a structure, at least not one that is evident, and their nature is neither numeric nor categorical. For example, data under qualitative study could include written textual, visual, or audio data. This type of analysis must therefore be based on methodologies, often ad hoc, to extract information that will generally lead to models capable of providing qualitative predictions, with the result that the conclusions to which the data analyst can arrive may also include subjective interpretations. On the other hand, qualitative analysis can explore more complex systems and draw conclusions that are not possible using a strictly mathematical approach. Often this type of analysis involves the study of systems such as social phenomena or complex structures that are not easily measurable.

统计代写|Matplotlib代写|Python and Data Analysis

The main argument of this book is to develop all the concepts of data analysis by treating them in terms of Python. The Python programming language is widely used in scientific circles because of its large number of libraries that provide a complete set of tools for analysis and data manipulation.

Compared to other programming languages generally used for data analysis, such as $\mathrm{R}$ and MATLAB, Python not only provides a platform for processing data, but also has features that make it unique compared to other languages and specialized applications. The development of an ever-increasing number of support libraries, the implementation of algorithms of more innovative methodologies, and the ability to interface with other programming languages ( $\mathrm{C}$ and Fortran) all make Python unique among its kind.
Furthermore, Python is not only specialized for data analysis, but also has many other applications, such as generic programming, scripting, interfacing to databases, and more recently web development, thanks to web frameworks like Django. So it is possible to develop data analysis projects that are compatible with the web server with the possibility to integrate it on the Web.
So, for those who want to perform data analysis, Python, with all its packages, is considered the best choice for the foreseeable future.

统计代写|Matplotlib代写|Python—The Programming Language

The Python programming language was created by Guido Von Rossum in 1991 and started with a previous language called $\mathrm{ABC}$. This language can be characterized by a series of adjectives:

  • Interpreted
  • Portable
  • Object-oriented
  • Interactive
  • Interfaced
  • Open source
  • Easy to understand and use

Python is an interpreted programming language, that is, it’s pseudo-compiled. Once you write the code, you need an interpreter to run it. The interpreter is a program that is installed on each machine that has the task of interpreting the source code and running it. Unlike with languages such as $\mathrm{C}, \mathrm{C}++$, and Java, there is no compile time with Python. Python is a highly portable programming language. The decision to use an interpreter as an interface for reading and running code has a key advantage: portability. In fact, you can install an interpreter on any platform (Linux, Windows, and Mac) and the Python code will not change. Because of this, Python is often used as the programming language for many small-form devices, such as the Raspberry Pi and other microcontrollers.

Python is an object-oriented programming language. In fact, it allows you to specify classes of objects and implement their inheritance. But unlike $\mathrm{C}++$ and Java, there are no constructors or destructors. Python also allows you to implement specific constructs in your code to manage exceptions. However, the structure of the language is so flexible that it allows you to program with alternative approaches with respect to the object-oriented one. For example, you can use functional or vectorial approaches. Python is an interactive programming language. Thanks to the fact that Python uses an interpreter to be executed, this language can take on very different aspects depending on the context in which it is used. In fact, you can write code made of a lot of lines, similar to what you might do in languages like $\mathrm{C}_{++}$or Java, and then launch the program, or you can enter the command line at once and execute it, immediately getting the results of the command. Then, depending on the results, you can decide what command to run next. This highly interactive way to execute code makes the Python computing environment similar to MATLAB. This feature of Python is one reason it’s popular with the scientific community.

Python is a programming language that can be interfaced. In fact, this programming language can be interfaced with code written in other programming languages such as $\mathrm{C} / \mathrm{C}_{+}$and FORTRAN. Even this was a winning choice. In fact, thanks to this aspect, Python can compensate for what is perhaps its only weak point, the speed of execution. The nature of Python, as a highly dynamic programming language, can sometimes lead to execution of programs up to 100 times slower than the corresponding static programs compiled with other languages. Thus the solution to this kind of performance problem is to interface Python to the compiled code of other languages by using it as if it were its own.

本书的主要论点是通过用 Python 来处理数据分析的所有概念。Python 编程语言在科学界被广泛使用,因为它拥有大量的库,为分析和数据操作提供了一套完整的工具。

与其他通常用于数据分析的编程语言相比,例如R与 MATLAB 一样,Python 不仅提供了一个处理数据的平台,而且与其他语言和专业应用程序相比,它还具有使其独一无二的特性。越来越多的支持库的开发,更多创新方法的算法的实现,以及与其他编程语言交互的能力(C和 Fortran)都使 Python 在同类中独一无二。
此外,Python 不仅专门用于数据分析,而且还有许多其他应用程序,例如通用编程、脚本、数据库接口,以及最近的 Web 开发,这要归功于 Django 等 Web 框架。因此,可以开发与 Web 服务器兼容的数据分析项目,并可以将其集成到 Web 上。
因此,对于那些想要执行数据分析的人来说,Python 及其所有软件包被认为是可预见的未来的最佳选择。

Python 编程语言由 Guido Von Rossum 于 1991 年创建,并从以前的语言开始,称为一种乙C. 这种语言可以用一系列形容词来描述:

  • 口译
  • 便携的
  • 面向对象
  • 交互的
  • 接口
  • 开源
  • 易于理解和使用

Python 是一种解释型编程语言,也就是说,它是伪编译的。编写代码后,您需要一个解释器来运行它。解释器是安装在每台机器上的程序,其任务是解释和运行源代码。与语言不同,例如C,C++和Java,Python没有编译时间。Python 是一种高度可移植的编程语言。使用解释器作为读取和运行代码的接口的决定有一个关键优势:可移植性。事实上,您可以在任何平台(Linux、Windows 和 Mac)上安装解释器,并且 Python 代码不会改变。正因为如此,Python 经常被用作许多小型设备的编程语言,例如 Raspberry Pi 和其他微控制器。

Python 是一种面向对象的编程语言。事实上,它允许您指定对象的类并实现它们的继承。但不像C++和 Java,没有构造函数或析构函数。Python 还允许您在代码中实现特定的结构来管理异常。但是,该语言的结构非常灵活,它允许您使用相对于面向对象的替代方法进行编程。例如,您可以使用函数或矢量方法。Python 是一种交互式编程语言。由于 Python 使用解释器来执行这一事实,这种语言可以根据使用它的上下文呈现出非常不同的方面。事实上,您可以编写由很多行组成的代码,类似于您在语言中所做的事情,例如C++或者Java,然后启动程序,也可以直接进入命令行执行,立即得到命令的结果。然后,根据结果,您可以决定接下来要运行什么命令。这种高度交互的代码执行方式使得 Python 计算环境类似于 MATLAB。Python 的这一特性是它受到科学界欢迎的原因之一。

Python是一种可以接口的编程语言。事实上,这种编程语言可以与用其他编程语言编写的代码进行交互,例如C/C+和 FORTRAN。即使这是一个成功的选择。事实上,多亏了这一点,Python 可以弥补它唯一的弱点,即执行速度。Python 作为一种高度动态的编程语言,其性质有时会导致程序的执行速度比用其他语言编译的相应静态程序慢 100 倍。因此,这种性能问题的解决方案是将 Python 与其他语言的编译代码接口,就像使用它自己一样。

术语 广义线性模型(GLM)通常是指给定连续和/或分类预测因素的连续响应变量的常规线性回归模型。它包括多元线性回归,以及方差分析和方差分析(仅含固定效应)。



有限元是一种通用的数值方法,用于解决两个或三个空间变量的偏微分方程(即一些边界值问题)。为了解决一个问题,有限元将一个大系统细分为更小、更简单的部分,称为有限元。这是通过在空间维度上的特定空间离散化来实现的,它是通过构建对象的网格来实现的:用于求解的数值域,它有有限数量的点。边界值问题的有限元方法表述最终导致一个代数方程组。该方法在域上对未知函数进行逼近。[1] 然后将模拟这些有限元的简单方程组合成一个更大的方程系统,以模拟整个问题。然后,有限元通过变化微积分使相关的误差函数最小化来逼近一个解决方案。





随机过程,是依赖于参数的一组随机变量的全体,参数通常是时间。 随机变量是随机现象的数量表现,其时间序列是一组按照时间发生先后顺序进行排列的数据点序列。通常一组时间序列的时间间隔为一恒定值(如1秒,5分钟,12小时,7天,1年),因此时间序列可以作为离散时间数据进行分析处理。研究时间序列数据的意义在于现实中,往往需要研究某个事物其随时间发展变化的规律。这就需要通过研究该事物过去发展的历史记录,以得到其自身发展的规律。


多元回归分析渐进(Multiple Regression Analysis Asymptotics)属于计量经济学领域,主要是一种数学上的统计分析方法,可以分析复杂情况下各影响因素的数学关系,在自然科学、社会和经济学等多个领域内应用广泛。
