Parameters

Description

Parameters that are shared by multiple functions

Arguments

obs.y

Observed data matrix with ll rows and 4 columns. Row kk in the matrix represents the observed data from dose level kk. The columns are

  • column 1: number of patient with no DLT, no immune response

  • column 2: number of patient with no DLT, immune response

  • column 3: number of patient with DLT, no immune response

  • column 4: number of patient with DLT, immune response

prob.mdl

Option of the probability models:

  • NONPARA: non-parametric+ model

  • NONPARA+: non-parametric model

  • PARA: partially parametric model

  • PARA+: partially parametric+ model

Default value is NONPARA. See visit for details.

priors

A class VTPRIOR object created by vtPriorPar for PARA and PARA+ model.

etas

Vector of length 2 representing (pL,pU)(p_L, p_U). pLp_L: lower bound of DLT risk, below which the current dose is considered absolutely safe; pUp_U: upper bound of DLT risk above which the current dose is considered too toxic

prev.res

Response rate from the next lower dose level, say, l1l-1. This can be a scalar representing the mean of the response rate E(q(l1))E(q^{(l-1)}), or a vector of posterior samples of the response rate q(l1)q^{(l-1)}. For l=1l=1, this value is set to 00.

dec.cut

Thresholds C1,C2,C3C_1,C_2,C_3. If the vector length is shorter than 33, it is repeated to have 33 elements. See visit for details.

digits

Digits for print

seed

Random seed
