Constructor & Destructor Documentation

NUM_NAMESPACE_BEGIN exponential_distribution::exponential_distribution ( double  m = 1.0  ) 

Create a distribution with the given mean.

Parameters:
mean the mean.
Create a distribution with the given mean.
Parameters:
m the mean.

Member Function Documentation

double exponential_distribution::cdf ( double  x  )  const [virtual]

The CDF for this distribution. This method returns P(X < x).

Parameters:
x the value at which the CDF is evaluated.
Returns:
CDF for this distribution.

Implements continuous_distribution.

double exponential_distribution::inverse_cdf ( double  p  )  const [virtual]

The inverse CDF for this distribution. This method returns x such that, P(X < x) = p.

Parameters:
p the cumulative probability.
Returns:
x

Implements continuous_distribution.

double exponential_distribution::mean (  )  const

Access the mean.

Returns:
the mean.

void exponential_distribution::mean ( double  m  ) 

Modify the mean.

Parameters:
mean the new mean value.
Modify the mean.
Parameters:
m the new mean value.
