    Help with Probabilistic Modeling with many elements in simulation with unknown probs.

    I'm wanting to create a probabilistic model based on several simulations, where I have a binary outcome (go or no-go) and a variable input. The old way of formulating the proability distribution was a straight-forward, curve-fitting of the input variable versus the "go or no-go" outcomes...

    Congruential Generators.

    Find all of the cycles of the following congruential generators. For each cycle identify which seeds X_0 lead to that cycle. (a). X_{n+1} = 9X_n + 3\mod 11 (b). X_{n+1} = 8X_n + 3\mod 11 (c). X_{n+1} = 8X_n + 2\mod 12 How can i choose the seed,X_0, at random ? ###When will i stop to...

    Simulating correlated lifetimes at pre-specified correlation level

    I am trying to simulate remission times for 100 patients from an exponential distribution with mean 1 year. I also want to simulate after-remission times for these 100 patients. But it is very much likely in the real life scenario that those who remit quickly are likely to have comparatively...

    Simulation of remission and after remission times under specific conditions

    This is basically a data generation problem. Say, t is an exponential lifetime with mean two years. tr is the remission time and ts is the after remission time. So, t=tr+ts. I need to simulate these quantities for 100 patients. Now in real life, usually when tr is smaller, that is when the...
