Optimal design is the judicious allocation of resources to achieve the objectives of studies using minimal cost via careful statistical planning. Researchers and practitioners in various fields of applied science are now beginning to recognize the advantages and potential of optimal experimental design. Applied Optimal Designs is the first book to catalogue the application of optimal design to real problems, documenting its widespread use across disciplines as diver 606 $aOptimal designs (Statistics) 606 $aExperimental design 608 $aElectronic books. 615 0$aOptimal designs (Statistics) 615 0$aExperimental design. 676 $a519.5/7 676 $a519.57 701 $aBerger$b Martijn$0977642 701 $aWong$b Weng Kee$0927233 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910143748103321 996 $aApplied optimal designs$92227327 997 $aUNINA
