Applied regression and generalized linear models

1. Download the two datasets train.csv and test.csv from https://www.kaggle.

com/c/titanic/data (this is the competition Titanic: Machine Learning from

Disaster from Kaggle). Based on the training data, build a reasonable model

based on logistic regression for the survival status based on the explanatory

variables (you can start with a basic model and subsequently either expand it

using interactions etc. and/or perform model selection to remove some vari-

ables). Describe your model. Use your model to predict the survival status for

the subjects present in the test dataset. Report your prediction accuracy score.
