Detailed Description

Parameter transformation from ] b, +inf [ or ] -inf, b [ to ]-inf, + inf [.

The equation of the tranformation is

\[ x' = \begin{cases} \log(a\cdot(x-b)) & \text{if $x < b+1$},\\ a(x-1-b) & \text{if $a \geq b+1$}. \end{cases} \]

for a transformation from ] b, +inf [ to ]-inf, + inf [. The 'b' parameter is the lower bound and 'a' is a scaling factor set to 1 by default. For a transformation from ] -inf, b [, the transformation is then

\[ x' = \begin{cases} -\log(-a\cdot(x-b)) & \text{if $x < b-1$},\\ -a(x-1-b) & \text{if $a \geq b-1$}. \end{cases} \]

◆ RTransformedParameter()

bpp::RTransformedParameter::RTransformedParameter ( const std::string &  name,
double  value,
double  bound = 0,
bool  positive = true,
double  scale = 1 
)
inline

Build a new RTransformedParameter, with given bound and scale.

Parameters
namethe name of the parameter.
valuethe value of th eparameter, in orginal coordinates.

Member Function Documentation

◆ addParameterListener()

virtual void bpp::Parameter::addParameterListener ( ParameterListener listener,
bool  attachListener = true 
)
inlinevirtualinherited

Add a new listener to this parameter.

Parameters
listenerThe listener to add.
attachListenerTell if the parameter will own this listener. If so, deep copies will be made when cloning the parameter, and the listener will be destroyed upon destruction of the parameter or upon removal. Alternatively, only superficial copies will be made, and the listener will persist if the parameter is destroyed.
