In real estates, housing market prediction (forecasting) is crucial. There are many factors that may influence the house prices. The datasets housing.training.csv and housing.testing.csv contain 25 quantitative explanatory variables describing many aspects of residential homes in Ames, IA.
The goal of this project is to predict house prices. To this end, we will be using regression analysis.
For each R output result, you may either type directly into a Word document or take a screenshot. If you take the screenshot, make sure that the current date is shown.
Ensure everything is clearly labeled. The report must be 10-12 pages long, including a title page and reference page (the report itself should be 8-10 pages). Cite 2-3 academic sources other than the textbook, course materials, or other information provided as part of the course materials. Follow APA format, according to CSU Global Writing Center (Links to an external site.).

From this data we try to see the correlation between the type of transmission the car has versus how much gas it saves or spends but we can only tell from the scatter plot that automatic seems to get better mpg or skews towards higher mpg. This is one of the reasons that a simple linear regression model may not fit our analysis because it is not always representing a complete description of the relationship amongst the variables (Flom, 2019). There are many factors this graph does not show that could attribute to the variance in mpg such as the mt car being a sports car, having a bigger engine, or being a bigger car in general just to name a few factors. Module 4: Option #1: Logistic Regression 3 We would classify the transmission as automatic when we test with the mpg value of 16 because of how low the probability of it being a manual is. With their only being 2 variables of 1 or 0 for Module 4: Option #1: Logistic Regression the transmission it forces us to use 0.5 as the cut off value which the car with 16 mpg likely exceeds. 4 Module 4: Option #1: Logistic Regression 5 References Flom, P.

Most of the house were sold at a median price whole very few were sold any higher than 400,000 dollars.
