STAT 545A Homework 1

My first R Markdown Document. Here's how to make one:

• open RStudio
• select File > New > R Markdown
• paste the R code in the skeleton.
• click Knit HTML to preview the page
• save the HTML locally and / or publish to RPubs

n <- 50
a <- 2
b <- -3
sigSq <- 0.5
x <- runif(n)
y <- a + b * x + rnorm(n, sd = sqrt(sigSq))
(avgX <- mean(x))

## [1] 0.4864

kntr takes the code in the .Rmd document and makes a .md document and figures.

plot(x, y)
abline(a, b, col = "red")
