Allocate treatments according to weighted L-optimal objective function allowing for a pseudo-nonmyopic approach. We assume a logistic model for the response and continuous treatment.
1 2 3 |
covar |
a dataframe for the covariates |
true.beta |
the true parameter values of the data generating mechanism |
threshold |
the cut-off value for hypothesis tests |
kappa |
the value of probability at which weights are set at zero |
init |
the number of units in the initial design |
sim |
number of trajectories to simulate |
z.probs |
vector of probabilities for each level of covariate z |
k |
number of "outer loops" in the coordinate exchange algorithm |
wt |
set to T if the above lossfunction is weighted, NULL otherwise |
prior.scale |
the prior scale parameter |
same.start |
the design matrix to be used for the initial design. If set to NULL, function generates initial design. |
rand.start |
If set to T, function generates an initial design randomly. Else, coordinate exchange is used. |
bayes |
set to T if bayesglm is used instead of glm. Default prior assumed. |
u |
vector of uniform random numbers for generating responses. If set to NULL, responses generated from the binomial distribution. |
prior.default |
set to T if default priors for bayesglm is used. If set to False and bayes=T, normal priors used. |
true.bvcov |
if set to T, use the true parameter values to compute obejctive function. If set to NULL, use estimated parameter values. |
... |
further arguments to be passed to <lossfunc> |
Design matrix D, value of weighted L-optimal objective function
