Member Function Documentation

double geometric_distribution::cdf

(

int

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 discrete_distribution.

int geometric_distribution::inverse_cdf

(

double

p

)

const [virtual]

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

Parameters:

p

the cumulative probability.

Returns:

x

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

Parameters:

p

the cumulative probability.

Returns:

x

Implements discrete_distribution.

double geometric_distribution::pmf

(

int

x

)

const [virtual]

The PMF for this distribution. This method returns P(X = x).

Parameters:

x

the value at which the PMF is evaluated.

Returns:

PMF for this distribution.

Implements discrete_distribution.

double geometric_distribution::probability_of_success

(

)

const

Access the probability of success.

Returns:

the probability of success.

void geometric_distribution::probability_of_success

(

double

p

)

Modify the probability of success.

Parameters:

p

the new probability of success.

Modify the probability of success.

Parameters:

df

the new probability of success.
