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).*

Use R to do the procedures listed below. Load your data set on the R compiler as vector x Determine the mean, variance, and standard deviation of x. Plot the values of x on the vertical axis against the index values (i.e. the observation number: 1, 2, ... n) on the horizontal axis. Add to your plot a horizontal line representing the mean of x colored red. Annotate your R script to document each procedure and to interpret your results...
