zero_d¶

covid_19_simulations.zero_d.
infect
(df, trans_rate, day_name)[source]¶ Simulates a single day of infection. Each infected person
NOTE: a 0 counts as infected, while a 1 is healthy.
- Inputs:
- df : (pandas DataFrame) object holding all values of infected people. Each
- column of “infected day _” corresponds to a different day, with “_” being some integer or float. The “name” column assigns a name to each object, independent of index. In the infected columns, a 0 counts as infected, while a 1 is healthy.
- trans_rate : (float) rate of transmission between individuals. infection
- is performed in a probabilistic manner, casting it as a draw from a binomial distribution with a rate of 1 - trans_rate.
- day_name : (float or int) the day of this infection, used to create a new
- column in the dataframe tracking the day’s infections.
- Outputs:
- df : (pandas DataFrame) object, same as the input, but with a new column
- holding this day’s infected results.

covid_19_simulations.zero_d.
simulate
(N, trans_rate, t_steps, N_initial)[source]¶ Simulates an infection run.
- Inputs:
N : (int) number of individuals in the system. trans_rate : (float) rate of transmission between individuals. infection
is performed in a probabilistic manner, casting it as a draw from a binomial distribution with a rate of 1 - trans_rate.t_steps : (int) number of time steps (“days”) to consider. N_initial : (int) number of initially infected individuals.
- Outputs:
- df : (pandas DataFrame) object holding all values of infected people. Each
- column of “infected day _” corresponds to a different day, with “_” being some integer or float. The “name” column assigns a name to each object, independent of index. In the infected columns, a 0 counts as infected, while a 1 is healthy.
one_d¶

animate_histogram
(df, title)[source]¶ animates a histogram.

infect1D
(df, trans_rate, day_name, thresh, power)[source]¶ Simulates a single day of infection in 1D.
NOTE: a 0 counts as infected, while a 1 is healthy.
- Inputs:
- df : (pandas DataFrame) object holding all values of infected people. Each
- column of “infected day _” corresponds to a different day, with “_” being some integer or float. The “name” column assigns a name to each object, independent of index. In the infected columns, a 0 counts as infected, while a 1 is healthy.
- trans_rate : (float) rate of transmission between individuals. infection
- is performed in a probabilistic manner, casting it as a draw from a binomial distribution with a rate of 1 - trans_rate.
- day_name : (float or int) the day of this infection, used to create a new
- column in the dataframe tracking the day’s infections.
- Outputs:
- df : (pandas DataFrame) object, same as the input, but with a new column
- holding this day’s infected results.

simulate1D
(N, trans_rate, t_steps, N_initial, thresh, power, distrib_pop, distrib_infec, kwargs_for_pop={}, kwargs_for_infec={})[source]¶ Simulates an infection run in 1D.
- Inputs:
N : (int) number of individuals in the system. trans_rate : (float) rate of transmission between individuals. infection
is performed in a probabilistic manner, casting it as a draw from a binomial distribution with a rate of 1 - trans_rate.t_steps : (int) number of time steps (“days”) to consider. N_initial : (int) number of initially infected individuals. thresh : (float) distance less than which infection is transmitted at the trans_rate;
that is, less than which this function returns a value of 1. At a distance greater than this, this function returns 1/distance^power.- power : (float) Greater than 0. Power to which the multiplier falls off if the distance
- is greater than some threshold.
distrib_pop : (func) distribution function to determine how individuals are initialized. distrib_infec : (func) distribution function to determine how initial infections are initialized. kwargs_for_pop : (dict) keyword arguments passed to the distrib_pop distribution type.
Size not included.- kwargs_for_infec : (dict) keyword arguments passed to the distrib_infect distribution type. Size not
- included.
- Outputs:
- df : (pandas DataFrame) object holding all values of infected people. Each
- column of “infected day _” corresponds to a different day, with “_” being some integer or float. The “name” column assigns a name to each object, independent of index. In the infected columns, a 0 counts as infected, while a 1 is healthy.
