    What is this time series coding doing

    Let's be clear. I explained what the () surrounding the entire code chunk was doing. I didn't mention the square brackets at all. Which were you asking about

    What is this time series coding doing

    I find it odd that you typed that out instead of copy/pasting. You missed the closing parenthesis on each of the quotes. But to answer the question by wrapping everything in parenthesis it will automatically print the results. Typically if you store a result into a variable you don't...

    discrete probability function P(X=i) =(1/2)^i for i = 1,2,3 X³ e [-9,9]

    Nothing is bad about simple solution when the problems aren't complex.

    Problem with package

    So monthdays is a function. So you need to supply it an argument (or at least call the function somehow). I really don't know what you were trying to do with your code. Can you explain in plain words what you were trying to achieve?

    I would love to hear your reasoning for asking about why you should or should not use the Poisson distribution.

    Simple question. Type of data?

    Yeah... entirely ordinal. Just because somebody attaches numbers to something doesn't make it continuous.

    Absolute dumbest question so be gentle

    That depends on what your goal is.
