Logistic Regression with Principal Components

Preparation Code

# Sample Data
library(titanic)

Actual Code

1. Run the logistic regression model.

fit <- glm(Survived ~ Sex + Age, family = "binomial", titanic_train)
summary(fit)

2. If required, perform prediction.

Sample Task 1

Perform prediction on 1 new observation.

predict(fit, newdata = data.frame(Sex = "male", Age = 35))

Sample Task 2

Perform prediction on a test set.

predict(fit, newdata = titanic_test)
