Abstract:<\/strong><\/span> Noted Optimal Design Theorist C S Cheng and his research collaborator M H Kao investigated the scope of study of optimal experimental designs in the context of fMRI studies.\u00a0 We intend to review some aspects of this problem and, that too, from a small sample perspective.\u00a0 An experimental subject [patient] is presented with a mental stimulus [e.g. picture] for a certain duration of time. During this presentation, the patient absorbs a sequence of mental stimuli along with a provision for intermediate \u2018resting periods\u2019 as well. The measurement refers to the \u2018output\u2019 in a well-specified reference \u2018brain voxel\u2019 and the purpose is to examine the response profiles to understand the nature and extent of local brain activity in response to the stimuli.
\nA linear model is envisaged and its purpose is to explain the mean response in terms of a constant [unknown parametric effect] and, additionally, a set of what are referred to as \u2018h-parameters\u2019. The h-parameters are also unknown. The inference problems center around h-parameters. Usual optimality considerations [such as A- and D-optimality] apply.
\nIn this presentation the linear model will be presented, estimation issues will be discussed and related concepts such as ‘orthogonality’ and ‘balance’ will be elaborated.<\/div>\n<\/td>\n
