Using R programming language, supply the code for: Generate a random sample of size 10, 000 from gamma distribution with scale parameter equal to 1 and shape parameter equal to 2, and form it into a 1000 x 10 matrix. Use the apply() function on this matrix to compute the means of the 1000 rows. Note that the resulting vector comprises the mean of 1000 random samples of size 10 from the above distribution. Examine the distribution of the sample...

The value of the R function "mean" applied to a vector $\mathbf{v}=(v_1,v_2,...v_n)$ is the arithmentic mean of the vector: $\bar{v}=\frac{1}{n} \sum_{i=1}^nv_i$. The value of the R function "var" applied to the vector $\mathbf{v}$ equals $\frac{1}{n-1} \sum_{i=1}^n(v_i-\bar{v})^2$, a measure of how much the values differ from the mean. For $\lambda\in\{4,25,100\}$, create samples of size 100,000 from the Poisson distribution with parameter $\Lambda$ and the Normal distribution with mean equal to $\lambda$ and sd equal to $\sqrt{\Lambda}$. Please compare the values of...

R programming Language Problem 1. Create three vectors, each containing 20 values randomly sampled from a normal distribution. The first should be from a normal distribution with mean = 0 and standard deviation = 1 (a.k.a. the standard normal distribution). The second should be from a normal distribution with mean = 10 and standard deviation = 1. The third should be from a normal distribution with mean = 10 and standard deviation = 10. Use the mean() and sd() functions...

how to randomly generate moves until the whole board is filled?. If the board size is c*r, you can only call the random function rand() c*r times (excluding the random function rand() that have been used in the provided code). Below is the code I need to convert.

R programming 1. Write an assignment statement to complete each of the following without using diff() and sign(): (a) generate a vector of the difference between the ith element and the (i+1)th element in a vector v of integers, where i = 1: length(v), and (b) generate a vector of the sign of each elements in the vector generated in (a) as follows: ‘p’ for positive, ‘n’ for negative. (Use v ⟵ c(1,4,7,2,1) for testing.) 2. Write a function that...
