When do you call a variable a deterministic variable?
Deterministic variable If the outcome of a variable is fixed, i.e. if a variable will always have the exact same value, we call this a deterministic variable. Random or stochastic variable
What’s the difference between a variable and a random variable?
If the outcome of a variable is fixed, i.e. if a variable will always have the exact same value, we call this a deterministic variable. A random variable is a variable, which may take a range of numerical outcomes as the value is a result of a random phenomenon.
Which is an example of a deterministic probability system?
Deterministic: All data is known beforehand Once you start the system, you know exactly what is going to happen. Example. Predicting the amount of money in a bank account. If you know the initial deposit, and the interest rate, then: You can determine the amount in the account after one year.
Which is a real valued random variable in the probability space?
Suppose now that X and Y are real-valued random variables for the experiment (that is, defined on the probability space) with means E(X), E(Y) and variances var(X), var(Y), respectively.
How many random numbers are used in a simulation?
Simulations use a lot of random numbers; one study found that most network simulations spend as much as 50% of the CPU generating random numbers. Simulation users need to be concerned with the quality of the (pseudo) random numbers and the independence between different streams of random numbers.
Which is the default random variable in ns-3?
by default, ns-3 simulations use a fixed seed; if there is any randomness in the simulation, each run of the program will yield identical results unless the seed and/or run number is changed. in ns-3.3 and earlier, ns-3 simulations used a random seed by default; this marks a change in policy starting with ns-3.4.
