Member Function Documentation

double f_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 f_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 f_distribution::denominator_degrees_of_freedom

(

)

const

Access the denominator degrees of freedom.

Returns:

the denominator degrees of freedom.

void f_distribution::denominator_degrees_of_freedom

(

double

df

)

Modify the denominator degrees of freedom.

Parameters:

df

the new denominator degrees of freedom.

double f_distribution::numerator_degrees_of_freedom

(

)

const

Access the numerator degrees of freedom.

Returns:

the numerator degrees of freedom.

void f_distribution::numerator_degrees_of_freedom

(

double

df

)

Modify the numerator degrees of freedom.

Parameters:

df

the new numerator degrees of freedom.
