Public Functions Documentation¶

function dgenint¶

Compute the probability of the generation interval.

inline double dgenint (
    int g,
    double S,
    double p_c,
    double p_i,
    double p_r,
    double & p_0_approx,
    double & normalizing,
    int max_contacts=200,
    int max_days=200
)

If p_0_approx is negative, it will be computed using the Poisson distribution. If normalizing is negative, it will be computed on the fly

Parameters:

g Generation interval
S Population size
p_c Probability of contact
p_i Probability of infection
p_r Probability of recovery
p_0_approx Approximation of the probability of not being infected
normalizing Normalizing constant
max_contacts Maximum number of contacts
max_days Maximum number of days

Returns:

The probability of the generation interval

function dpois¶

Compute the Poisson probability.

inline double dpois (
    int k,
    double lambda,
    int max_n=100,
    bool as_log=false
)

Parameters:

k Number of events
lambda Rate
max_n Maximum number of events
as_log Return the log of the probability

Returns:

The Poisson probability

function gen_int_mean¶

Compute the mean of the generation interval.

inline double gen_int_mean (
    double S,
    double p_c,
    double p_i,
    double p_r,
    int max_days=200,
    int max_n=200
)

Parameters:

S Population size.
p_c Probability of contact.
p_i Probability of infection.

Returns:

The mean of the generation interval

function log_factorial¶

Compute the log of the factorial.

inline double log_factorial (
    int n
)

Parameters:

n Number

Returns:

The log of the factorial
