On Sequential Treatment Allocations in Clinical Trials [PDF]
, 1996 This dissertation treats baseline-dependent sequential designs of two-treatment parallel-group clinical trials. The treatment assignments are chosen in order to minimize the variance, in a linear model, of the treatment effect.

Adaptive numerical designs for the calibration of computer codes [PDF]
, 2018 AMS subject classifications. 62K99, 62L05, 60G15Making good predictions of a physical system using a computer code requires the inputs to be carefully specified. Some of these inputs, called control variables, reproduce physical conditions, whereas other

Asymptotic optimality of sequential designs for estimation
International Journal of Mathematics and Mathematical Sciences, Volume 18, Issue 1, Page 147-150, 1995., 1995 This paper is concerned with the problem of allocating a fixed number of trials between K independent populations from the exponential family, in order to estimate a linear combination of the means with squared error loss. Introducing independent conjugate priors, a batch sequential procedure is proposed and compared with the optimal.

International Journal of Stochastic Analysis, Volume 4, Issue 4, Page 357-361, 1991., 1991 The problem of designing an experiment to estimate the product of the means of two normal populations is considered. A Bayesian approach is adopted in which the product of the means is estimated by its posterior mean. A fully sequential design is proposed and shown to be asymptotically optimal.

Asymptotic optimality of experimental designs in estimating a product of means
International Journal of Stochastic Analysis, Volume 3, Issue 1, Page 15-25, 1990., 1989 In nonlinear estimation problems with linear models, one difficulty in obtaining optimal designs is their dependence on the true value of the unknown parameters. A Bayesian approach is adopted with the assumption the means are independent apriori and have conjuguate prior distributions.
