课程名称：初学者日常工作中最有用的SAS函数 课程概述：欢迎参加“初学者日常工作中最有用的SAS函数”课程。首先感谢您选择这门课程，希望您会喜欢和享受它。该课程是关于SAS函数的完整介绍，涵盖超过60个函数，专注于您日常工作中所需的内容。我将函数分为三类：字符函数、日期和时间函数，以及统计和数学函数。 在教学方法上，我相信实践的重要性。在每节课中，您将进行不同的作业，以评估对材料的理解。课程结束时，您将完成三个实际数据项目，以检验您对SAS函数的掌握程度。课程配有资料下载文件夹，其中包含课程学习过程中使用的所有SAS程序、项目指令、真实数据集及项目解决方案。 课程要求：您只需了解SAS基本操作，包括数据操作、写条件语句和循环。我们将在SAS Studio（也称为"SAS大学版"）上进行教学，这是一款免费的软件，若尚未下载，不用担心，我们会一起操作。 课程大纲： - 第一部分是介绍，涵盖课程内容及SAS大学版的安装与熟悉，最后会下载课程资料文件夹。 - 第二部分学习字符函数，包括提取子字符串、计算字符串中的字符和单词数量、删除和替换特定字符、连接字符串以及字符和数值变量之间的转换。 - 第三部分集中于日期和时间函数，从声明常量日期、时间和日期时间变量开始，随后学习常用函数、提取日期/时间部分以及复杂的区间函数。 - 第四部分专注于数学和统计函数，包括绘制分布、生成随机数、数字四舍五入以及p值和临界值的计算等。 您在课程中或完成后均可随时提出疑问，我会在几个小时内回复您，最多不超过24小时。感谢您的参与！
Welcome to the course "Most useful SAS functions in your daily work for beginners". First of all, I want to say thank you for choosing to take this course. I sincerely hope you will like and enjoy this course.In my opinion, it's most complete SAS course about the functions.In this course, you are going to learn a variety of SAS functions. We will cover more than 60 functions, and I will only concentrate on function that you need in your daily work. I divided the functions into three categories: Character functions, Date and Time functions, and Statistical and Mathematical functions.A few words about teaching method. I believe in practice. Therefore, during each lesson, you will have different assignments to see if you understand the material. I put a strong emphasis on practice. Moreover, at the end of the course, you will have three projects on real data. These projects should give you an indication of whether you have understood the SAS functions and are ready to implement them. This course has course folder, that you will download. You will find there all the material you are going to learn during the course. It contains all SAS programs we develop during the lessons. In addition you will find there instructions to projects, the real datasets you going to use during the projects and of course the solutions to the projects. What about the requirements of the course? You have to know only SAS Base. In simply words, you have to know data manipulation, write conditional statements, loops and no more than that.In this course, we are going to work on SAS Studio and sometimes called also "SAS University Edition". This is free version, and if so far you have not downloaded it, don't worry. We will do it together. It's pretty simple.Curriculum of the course:I divided the course into five sections: The first section is introduction. In this section, you are going to learn the content of the course. Another two lectures are about Installation & Familiarity with SAS University Edition. If you have SAS Studio and you got to work on it, you can skip these lectures and go straight to the video about downloading course folder. And in the last video of this section, we will download course folder and put it into SAS shared folder. As I said in the previous video, this folder contains real datasets for three projects, project's instructions and solutions, and of course, all the functions and examples, syntaxes of the functions, we are going to solve during the course.Last section, contains conclusions and discounts to my other courses. The rest three parts is a core of the course. In the second section, we are going to learn character functions. We will see, how to extract substrings from string, count the number of characters and words in the string, remove and replace specific characters in the string, how to concatenate character strings and numeric values, how to search a character expression within a string and how to convert numeric variable to character variable and vice versa.Third section concentrates on most useful date and time functions. We start from declaring constant date, time and datetime variables and after that, go straight to functions. We will learn most basic functions that returns date, time or datetime values based on parameters. We will also see, how can we extract ‘parts' from date, time or datetime values. We will also learn more complex SAS date, time or datetime functions that are asked in each job interview. These are Interval Functions. For example, these functions can determine how long a period has elapsed between two time points or advances a given date, time or datetime by a specified number of intervals.Fourth section dedicated to mathematical and statistical functions. We are going to draw distributions, generate random numbers from different distributions, round numbers. Also, we will talk about calculation of p-values and critical values and et cetera.Guys, you can ask me any questions you want during the course or even after you finish. I usually answer within a few hours, but no more than 24 hours.Thank you very
