Allocate treatments according to an information matrix based optimality criterion allowing for a pseudo-nonmyopic approach. We assume a logistic model for the response.

cr.simfuture.logis(covar, true.beta, threshold, kappa, init, int, cr.lossfunc,
  k, wt = T, sim, z.probs, same.start = NULL, rand.start = NULL,
  stoc = T, bayes = T, u = NULL, prior.default = T, coordex = NULL,
  true.bvcov = NULL, ...)

`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
`int`	set to T if you allow for treatment-covariate interactions in the model, NULL otherwise
`cr.lossfunc`	a function for the optimality criterion to minimize which is appropriate for linear combinations of parameters
`k`	number of "outer loops" in the coordinate exchange algorithm
`wt`	set to T if the above lossfunction is weighted, NULL otherwise
`sim`	number of trajectories to simulate
`z.probs`	vector of probabilities for each level of covariate z
`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.
`stoc`	set to T if treatments are allocated using a stochastic method where the probability is determined by the optimality crtierion. Set to F if treatments are allocated deterministically.
`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.
`coordex`	set to T if the coordinate exchange algorithm is used to assign treatments in the trajectory. Sequential approach used otherwsise.
`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>
