Haryatmi %A Gunardi %J Applied Mathematical Sciences %D 2013 %I %X Weighted exponential and generalized exponential functions are usedin life time data analysis. Both of these functions can be applied asa growth curve. Locally D-optimal designs for weighted exponentialand generalized exponential models are investigated. These designs areminimally supported. %K Local optimality %K D-optimality %K Nonlinear models %K General Equivalence Theorem %K Minimally supported designs %K Growth curve %U http://www.m-hikari.com/ams/ams-2013/ams-21-24-2013/widiharihAMS21-24-2013.pdf
