STATISTICS WITH R PROGRAMMING Lecture Notes

STATISTICS WITH R PROGRAMMING Lecture Notes Prepared by , Assistant Professor, CSE Department, GVPCEW. UNIT- I Introduction, How to run R, R Sessions and Functions, Basic Math, Variables, Data Types, Vectors, Conclusion, Advanced Data Structures, Data Frames, Lists, Matrices, Arrays, Classes Introduction: R is a PROGRAMMING language and environment commonly used in statistical computing, data analytics and scientific research. It is one of the most popular languages used by statisticians, data analysts, researchers and marketers to retrieve, clean, analyze, visualize and present data. Due to its expressive syntax and easy-to-use interface, it has grown in popularity in recent years. R is a PROGRAMMING language and software environment for statistical analysis , graphics representation and reporting.

SAS (Statistical Analysis System) SAS is a powerful software that has been the first choice of private enterprise for their analytics needs for a long time. Its GUI and comprehensive documentation, coupled with reliable technical support make it a very good tool for companies.

Exponential and Sinusoidal Signals: Exponential and sinusoidal signals are characteristic of real-world signals and also from a basis (a building block) for other signals. A generic complex exponential signal is of the form: where C and a are, in general, complex numbers. Lets investigate some special cases of this signal

Using Arrays in SAS® Programming Arrays provide an alternative method of referring to variables. Instead of referring to the first revenue variable as Rev1, you can refer to it by using the array name and an index into the array, such as REVENUE[I] (assuming that I has a value of 1).
