Assessment Questions: Simulation in R

I chose the following concept map: http://teaching.software-carpentry.org/2013/03/26/concept-map-simulation-in-r-noble/

Novice vs. Competent practitioner

1. What is the advantage of doing simulations in R?

2. How would you know the best way to extract your parameters before and after simulation?

Competent practitioner vs. Expert

1. What is the difference between a simulation that yields parameters ‘very close’ from the ones you created to another one that yields the ‘exact’ created parameters?

2. In case you want to share your code, how can you always have the same model output even though you are using random numbers?
