daily_stats

class daily_stats(days=None, verbose=True, reporter=None, save_inds=False, **kwargs)

Bases: Analyzer

Print out daily statistics about the simulation. Note that this analyzer takes a considerable amount of time, so should be used primarily for debugging, not in production code. To keep the intervention but toggle it off, pass an empty list of days.

To show the stats for a day after a run has finished, use e.g. daily_stats.report('2020-04-04').

Parameters:

• days (list) – days on which to print out statistics (if None, assume all)

• verbose (bool) – whether to print on each timestep

• reporter (func) – if supplied, a custom parser of the stats object into a report (see make_report() function for syntax)

• save_inds (bool) – whether to save the indices of every infection at every timestep (also recoverable from the infection log)

Example:

sim = cv.Sim(analyzers=cv.daily_stats())
sim.run()
sim['analyzers'][0].plot()

Methods

intersect(*args)

Compute the intersection between arrays of indices, handling either keys to precomputed indices or lists of indices. With two array inputs, simply performs np.intersect1d(arr1, arr2).

report(day=None)

Print out one or all reports – take a date string or an int

make_report(sim, stats, show_empty='count')

Turn the statistics into a report

transpose(keys=None)

Transpose the data from a list-of-dicts-of-dicts to a dict-of-dicts-of-lists

plot(fig_args=None, axis_args=None, plot_args=None, do_show=None, **kwargs)

Plot the daily statistics recorded. Some overlap with e.g. sim.plot(to_plot='overview').

Parameters:

• fig_args (dict) – passed to pl.figure()

• axis_args (dict) – passed to pl.subplots_adjust()

• plot_args (dict) – passed to pl.plot()

• do_show (bool) – whether to show the plot

• kwargs (dict) – passed to cv.options.with_style()
