The results indicate that one of the forms of the function has more stable parameters and only for this form it is reasonable to use, as an approximation, the linear regression theory to analyse the parameters. © 1995 Chapman & Hall.4101-4102engApproximation theoryMathematical modelsParameter estimationRegression analysisSystem stabilityJohnson-Mehl-Avrami equationSigmoidal functionReaction kineticsArtigo10.1007/BF00360714Acesso restrito2-s2.0-0029358415
