    Interpreting Results of Monte Carlo Simulation (R)

    Hello, I have conducted a Monte Carlo simulation in R based on the guidelines below and I am struggling to interpret my results. Consider the following data-generating process Y = β1 × X + u 1. Simulate 1000 samples of size n = 100 with β1 = 2, X ∼ N(100,15) and u ∼ N(0,8). 2. In each...

    SPSS insufficient memory Fisher exact test

    Hi All, I have been conducted analyses on a study using the Fisher Exact test but have currently encountered an issue with my larger contingency tables (3x7 and 3x9) as SPSS has insufficient memory to conduct the analyses. In this scenario it is best to use a Monte Carlo simulation on these...

    How to make my approach to Monte Carlo simulation and random sample generation more statistically robust?

    I´m building a MC simulation models in Excel VBA and R in parallel. Below is my current approach. Please let me know where the weaknesses lie. How could I make my approach more statistically robust without diverging too far from some simplicity? I am particularly concerned with (3) and (5)...

    Haunted by Cauchy – A medium level problem

    Hi Let's suppose X1 and X2 are two Normally distributed variables. [In general, X1 is from N(m1,s1^2) and X2 from N(m2, s2^2) where m1<m2 and s1^2≠s2^2.] However, let’s say, for the sake of starting the discussion, that both are Normally distributed N(1,2^2) and N(2,3^2). One of X1 or X2 is...
