R Documentation
Six-Parametric Weibull Function with Additive Shift
Description
A special version of the six-parametric Weibull function
which has a 7th parameter for additive vertical shifting.
It is intended mainly for internal use.
vector of function parameters, see weibull6 for
an explanation of parameters p[1] ... p[6];
p[7] is an additive constant.
lower
lower limit of the cumulative (integrated) function,
upper
upper limit of the cumulative (integrated) function.
Details
The function is intended for
internal use, i.e. for separate area calculations of the left and right branches.
Value
fweibull7 gives the function and aweibull7 its definite
integral (cumulative function or area under curve). Note that
integration is done numerically and that the function returns a
scalar, not a vector.
