Environmental Statistics with R: Simple Linear Regression

Joseph Ofungwu, Ph.D., PE

Course Outline

R is a free software environment for statistical computing and graphics. This course offers participants an irresistible 2-in-1 value package, namely a fundamental data analysis methodology, and a freely available high-powered software system to do all the computations! First, regression is a pivotal statistical technique because it is essentially the only practical way that we can establish inter-relationships between variables using only limited data samples, and subsequently generalize or extrapolate the results to the larger data populations or universe. This course ensures that you will never again be confused by any terminologies or statistics associated with simple linear regression.
