How to do the following in R: Write a function to generate a random sample of size n from the Gamma(α,1) distribution by the acceptance-rejection method. Generate a random sample of size 1000 from the Gamma(3,1) distribution. (Hint: you may use g(x) ∼ Exp(λ = 1/α) as your proposal distribution, where λ is the rate parameter. Figure out the appropriate constant c).

I imported a dataset named "multiple.txt" into R using the read.table function. The table contains 50 variables and 100 observations per variable. Each variable is named V1, V2, V3,...,V50. The goal is to implement multiple testing across all 50 variables using the t-stat equation T = (x-bar - 0)/(Sx/sqrt(n). I was wondering if you could post sample code to run the t-statistic equation comparing each variable sample mean to 0, making a vector with all 50 of the t-stats, and...

Write a function to find the indices of a time series in which the absolute value of the derivative is above a particular threshold. This is somewhat based on work we’ve done in this chapter. The function: (a) should be named where_deriv_large. (b) should take two arguments: times, data (in that order). (c) (509 only) should have a third argument in which the value of the threshold can be passed. (d) should return a tuple. The first element is the...

A uniform random variable on (0,1), X, has density function f(x) = 1, 0 < x < 1. Let Y = X1 + X2 where X1 and X2 are independent and identically distributed uniform random variables on (0,1). 1) By considering the cumulant generating function of Y , determine the first three cumulants of Y .

The function named myRandomNum that returns a random integer in the range [1, 100] is defined as follows: int myRandomNum () { return rand()%100 + 1; } Now, write a program (code fragment) that repeatedly generates and prints random integers in the range [1, 100]. The program must stop when the absolute value of the difference between successive printed values is less than 5. Two sample output is given to help you understand the problem: 1. The program can possibly...
