In RTMBdist: Distributions Compatible with Automatic Differentiation by 'RTMB'
abs_smooth R Documentation
Smooth approximation to the absolute value function
Description
Smooth approximation to the absolute value function
Usage
abs_smooth(x, epsilon = 1e-06)
Arguments
x
vector of evaluation points
epsilon
smoothing constant
Details
We approximate the absolute value here as
\vert x \vert \approx \sqrt{x^2 + \epsilon}
Value
Smooth absolute value of x.
Examples
abs(0)
abs_smooth(0, 1e-4)
