Simulation

A type, representing an output of a simulated randomization procedure.

A command SimulatedRandomization(target, label, trt, prb) initializes an instance of SimulatedRandomization:

• target is a vector of target allocation ratio;
• label is a string that describes the simulated randomization procedure;
• trt is a matrix of size $n\times K\times S$, representing treatment assignments;
• prb is an array of size $n\times K\times S$, representing allocation probabilities,

where

• $n$ is the number of subjects simulated;
• $K$ is the number of treatments simulated (equal to the length of the target allocation vector);
• $S$ is the number of simulations performed.

Function simulates a randomization procedure

Call:

simulate(rnd, nsbj, nsim, seed)

Arguments

• rnd::T where T <: Randomization: an object, representing a randomization procedure to be simulated.
• nsbj::Int64: number of subjects simulated.
• nsim::Int64: number of simulations performed.
• seed::Int64: a random seed (for reproducibility); a default is set to 314159.

Result

• an object, representing simlated randomization, an instance of SimulatedRandomization.

Function simulates a randomization procedure

Call:

simulate(rnd, nsbj, nsim, seed)

Arguments

• rnd::DLUD : an object, representing a DLUD randomization procedure to be simulated.
• nsbj::Int64: number of subjects simulated.
• nsim::Int64: number of simulations performed.
• seed::Int64: a random seed (for reproducibility); a default is set to 314159.

Result

• an object, representing simlated randomization, an instance of SimulatedRandomization.

Function simulates a set of randomization procedures

Call:

simulate(rnd, nsbj, nsim, seed)

Arguments

• rnd::Vector{<:Randomization}: a vector of instances of <:Randomization type; each instance represents a randomization procedure to be simulated.
• nsbj::Int64: number of subjects simulated.
• nsim::Int64: number of simulations performed.
• seed::Int64: a random seed (for reproducibility); a default is set to 314159.

Result

• a vector of instances of SimulatedRandomization type; each instance represents a simulated randomization procedure.
