Question 2
Explain whether each scenario is a classification or regression problem, and indicate whether we are most interested in inference or prediction. Finally, provide n and p.
(a)
We collect a set of data on the top 500 firms in the US. For each firm we record profit, number of employees, industry and the CEO salary. We are interested in understanding which factors affect CEO salary.
Answer:
This is an example of regression problem.As the salary is continuous variable. We are trying to identify the factors on which the salary is dependent. We want to find inference of independent variables on a dependent variable. n = 500. (number of observations). p = 4 (profit, number of employees, industry and the CEO salary).
(b)
We are considering launching a new product and wish to know whether it will be a success or a failure. We collect data on 20 similar products that were previously launched. For each product we have recorded whether it was a success or failure, price charged for the product, marketing budget, competition price, and ten other variables.
Answer:
This is a classification problem where we want to predict whether the product will be success or failure. n = 20 (no of products) p = 13 (price charged for the product, marketing budget, competition price, and ten other variables)
(c)
We are interest in predicting the % change in the USD/Euro exchange rate in relation to the weekly changes in the world stock markets. Hence we collect weekly data for all of 2012. For each week we record the % change in the USD/Euro, the % change in the US market, the % change in the British market, and the % change in the German market.
Answer:
This is a regression problem as % change is a continuous variable.we are interested in prediction. Quantitative output n = 52 (observations for each week of 2012) p = 4 ( the % change in the US market, the % change in the British market, and the % change in the German market)
Question 5
What are the advantages and disadvantages of a very flexible (versus a less flexible) approach for regression or classification? Under what circumstances might a more flexible approach be preferred to a less flexible approach? When might a less flexible approach be preferred?
Answer:
The advantages for a very flexible approach for regression or classification are obtaining a better fit for non-linear models, decreasing bias. The disadvantages for a very flexible approach for regression or classification are requires estimating a greater number of parameters, follow the noise too closely (overfit), increasing variance. A more flexible approach would be preferred to a less flexible approach when we are interested in prediction and not the interpretability of the results. A less flexible approach would be preferred to a more flexible approach when we are interested in inference and the interpretability of the results.
Question 6
Describe the differences between a parametric and a non-parametric statistical learning approach. What are the advantages of a parametric approach to regression or classification (as opposed to a nonparametric approach)? What are its disadvantages?
Answer:
A parametric approach reduces the problem of estimating f down to one of estimating a set of parameters because it assumes a form for f.
A non-parametric approach does not assume a functional form for f and so requires a very large number of observations to accurately estimate f.
The advantages of a parametric approach to regression or classification are the simplifying of modeling f to a few parameters and not as many observations are required compared to a non-parametric approach.
The disadvantages of a parametric approach to regression or classification are a potential to inaccurately estimate f if the form of f assumed is wrong or to overfit the observations if more flexible models are used.

pairs(auto[,1:8])
plot(auto$cylinders, auto$horsepower)
We can say that as the number of cylinders increase, horsepower increases in general
plot(auto$cylinders, auto$mpg)
From above we can see that as the number of cylinders increases , miles per gallon decreases.
plot(auto$year, auto$mpg)
#### (f) Suppose that we wish to predict gas mileage (mpg) on the basis of the other variables. Do your plots suggest that any of the other variables might be useful in predicting mpg? Justify your answer.
Yes we can predict mpg by other variables such as number of cylinders, displacement , origin, horsepower.
par(mfrow=c(2,2))
plot(auto$mpg, auto$cylinders)
plot(auto$mpg, auto$displacement)
plot(auto$mpg, auto$horsepower)
plot(auto$mpg, auto$year)
from above we can see that mpg is a function of displacement, cylinders, horsepower and year. So we may be able to predict the mpg as a function of all these variables.

The Boston data frame has 506 rows and 14 columns. Rows and Columns represent the housing values in suburbs of Boston.
(b) Make some pairwise scatterplots of the predictors (columns) in this data set. Describe your findings.
pairs(Boston)
crime could be related with age, dis, rad, tax, ptratio and medv while nox is related with indus. also indus are related with dis.
(c) Are any of the predictors associated with per capita crime rate? If so, explain the relationship
par(mfrow=c(2,2))
plot(Boston$age, Boston$crim)
plot(Boston$ptratio, Boston$crim)
plot(Boston$dis, Boston$crim)
plot(Boston$lstat, Boston$crim)
- Older homes area have higher crime rate
- Small weighted mean distance of five boston employment centers from the suburb has higher crime rate
- more low status population more likely to have high crime rate.
(D) Do any of the suburbs of Boston appear to have particularly high crime rates? Tax rates? Pupil-teacher ratios? Comment on the range of each predictor
par(mfrow=c(1,3))
hist(Boston$crim[Boston$crim>1], breaks=25)
hist(Boston$tax, breaks=25)
hist(Boston$ptratio, breaks=25)
most cities have low crime rates, but there is a long tail: 18 suburbs appear to have a crime rate > 20, reaching to above 80
there is a large divide between suburbs with low tax rates and a peak at 660-680
for pupil to teacher ration there is a smalll left skewness
(e) How many of the suburbs in this data set bound the Charles river?
dim(subset(Boston, chas == 1))## [1] 35 14About 35 suburbs in this dataset ound the Charles river.
(f) What is the median pupil-teacher ratio among the towns in this data set?
median(Boston$ptratio)## [1] 19.05(g) Which suburb of Boston has lowest median value of owneroccupied homes? What are the values of the other predictors for that suburb, and how do those values compare to the overall ranges for those predictors? Comment on your findings
