INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

Hi There this is my assignment, i attached the data set as well. I want to predict the possible cost: 

Select and justify at least 3 different prediction model types that are likely to best help with your stated problem objectives.

Configure your models (e.g. select attributes and/or other model parameters) that you expect will best deliver relevant insights and/or provide the lowest error rates, justifying your decisions. 

Run these models, discussing the model outputs and drawing, where possible, insights related to your problem.

Prepare and discuss at least 1 ensemble model, combining two or more of your prediction models.

Select a proper scoring rule to measure the accuracy of your models. Determine and comment on the best generalised error rate across your 4 prediction models and of your ensemble models.

--> means I also need error rates of my model

Discuss what steps you may have taken to improve your individual models.

Include any R-code you used to prepare your data in the code appendix.
