Member Function Documentation

double hypergeometric_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 hypergeometric_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 hypergeometric_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.

int hypergeometric_distribution::number_of_failures

(

)

const

Access the number of failures.

Returns:

the number of failures.

void hypergeometric_distribution::number_of_failures

(

int

n

)

Modify the number of failures.

Parameters:

n

the new number of failures.

int hypergeometric_distribution::number_of_successes

(

)

const

Access the number of successes.

Returns:

the number of successes.

void hypergeometric_distribution::number_of_successes

(

int

n

)

Modify the number of successes.

Parameters:

n

the new number of successes.

int hypergeometric_distribution::sample_size

(

)

const

Access the sample size.

Returns:

the sample size.

void hypergeometric_distribution::sample_size

(

int

n

)

Modify the sample size.

Parameters:

n

the new sample size.
