Monte Carlo Sampling for Itemset Support

Look at the data file T10.txt. It contains one line per transaction, and each transaction is a list of items that appear in it. You are to use monte carlo sampling to find the relative support of the item set $X = {39, 704, 825}$, as follows:

• Write a program to construct the sampling distribution of the relative support of $X$. Your program should draw 100 random samples of size 10,000 and compute the support of $X$ in each sample. Plot the sampling distribution of relative support of $X$.

• Based on the sampling distribution your program should compute the lower and upper bound for the support of $X$ at the 95% confidence level.

• Your program should find the mean and standard deviation of the possible relative support values of $X$ in the samples, and compare the mean with the actual relative support of $X$ in the database.

• Either accept or reject the hypothesis that the true relative support of $X$ is 0.0106 at the 95% confidence level.
