Exam in Applied Statistical Methods

The following statements can be used to read the datasets for the exam.

Problem 1: Linear Regression

s_data_url_root <- "https://charlotte-ngs.github.io/asmss2023/data"
s_data_url_p1 <- file.path(s_data_url_root, "asm_exam_p01.csv")
tbl_p1 <- readr::read_delim(file = s_data_url_p1, delim = ",")

## Rows: 12 Columns: 3
## ── Column specification ────────────────────────────────────────────────────────
## Delimiter: ","
## dbl (3): Cow, Acetone, Methane
## 
## ℹ Use `spec()` to retrieve the full column specification for this data.
## ℹ Specify the column types or set `show_col_types = FALSE` to quiet this message.

Problem 2:

s_data_url_root <- "https://charlotte-ngs.github.io/asmss2023/data"
s_data_url_p2 <- file.path(s_data_url_root, "asm_exam_p02.csv")
