Hi,
I have read the help page and it was helpful but, I am having concerns because each time I run this code I get the same value.
I expected that each time I run the code, I will get different values due to random sampling.
How do I get this randomization? The values shouldn’t be the same each time the code is run, correct?
result <- boot(n_data, statistic = DataSummary, R = 100).
Best,
Bryan Mac
