getExpStartVal R Documentation
Get starting values for an exponential model
Description
Obtains approximate starting values for exponential model
'y~a*exp(b*x)'
by linearizing the exponential model to
'ln(y)~ln(a)+bx'
and transforming parameter 'a'. Values generated with this function
may not be apropriate for other nonlinear models.
Usage
getExpStartVal(x, y)
Arguments
x
A vector or dataframe column of an independent variable
y
A vector or dataframe column of a dependent variable
Value
