WebThe ‘weights’ argument is used to specify that the variance of residuals should be proportional to fitted values (‘varPower’ variance function) Starting values for model parameters. Self starting routines are not used by ‘nlme()’ and thus we need to specify a named vector, holding the initial values of model parameters.
WebThe initial value of the model is y = a. y = a. If b > 1, b > 1, the function models exponential growth. As x x increases, the outputs of the model increase slowly at first, but then …
