Other Tidyverse courses

Available here and here

Tidyverse Fundamentals Track

Intermediate Tidyverse Toolbox Track

Refresher: General modeling framework

In general: $y = f(\vec{x}) + \epsilon$
Linear regression models: $y = \beta_0 + \beta_1 \cdot x_1 + \epsilon$

Parallel slopes model

Polynomial model

Tree models

DataCamp courses using other models

Courses with different $f()$ in $y = f(\vec{x}) + \epsilon$:

Refresher: Regression table

# Fit model:
model_score_1 <- lm(score ~ age, data = evals)

# Output regression table:
get_regression_table(model_score_1)

# A tibble: 2 x 7
