I will be using this blog to post about anything that I want to share in statistics. For starter, I will run a linear regression with the iris dataset. names(iris) ## [1] "Sepal.Length" "Sepal.Width" "Petal.Length" "Petal.Width" "Species" Let’s predict Sepal.Length with Petal.Length and Petal.Width. #separate into training and testing sets set.seed(1234) train_ind <- sample(nrow(iris), floor(0.8 * nrow(iris))) iris_train <- iris[train_ind,] iris_test <- iris[-train_ind,] #run linear regression iris_lm <- lm(Sepal.
