How do I set the problem in R? My data file is leverage.csv and the variables are: Date, SPX and VIX
Homework Answers
To input data in r when a file is "leverage.csv" then we have to use following command
Leverage <- read.csv(file = 'data/leverage.csv') head(Leverage)
Use " as.Date( ) " to convert strings to dates
eg. mydates <- as.Date(c("2007-06-22", "2004-02-13"))
# number of days between 6/22/07 and 2/13/04
days <- mydates[1] - mydates[2]

R Programming Exercise Book Problem 57 (Difficulty: Easy) A normal distribution has a standard deviation of 35 and mean of 15. From this generate 2 to 400 samples. After generating the samples utilize the plot command to plot the mean of the generated sample (x-axis) against the number of samples. Create a second plot of the density of the 400 samples that you generated. This code can be solved in 4 to 8 lines. For this problem use the following...

NEED R CODE PLEASE ## Problem 4 *For the `homedata` (**UsingR**) data set find 90% confidence intervals for both variables `y1970` and `y2000`, assuming the sample represents some population. Perform one sample t-test for each variable, use `t.test()`, but first discuss whether the model assumptions are appropriate (include some check of the assumptions, like a Q-Q plot).*

Exercise 1. For this exercise use the bdims data set from the openintro package. Type ?bdims to read about this data set in the help menu. Of interest are the variables hgt (height in centimeters), wgt (weight in kilograms), and sex (dummy variable with 1-male, 0-female). Since ggplotO requires that a categorical variable be coded as a factor type in R, run the following code: library (openintro) bdíms$sex2 <-factor (bdins$sex, levels-c (0,1), labels=c('F', 'M')) (a) Use ggplot2 to make a...
