min_bic: minimize BIC for ARIMA models with default differencing order...

In vjcitn/sars2app: COVID-19 data resources and analysis tools cut down for an interactive app

Description

minimize BIC for ARIMA models with default differencing order 1 over choices of MA and AR order

Usage

min_bic(
  src,
  fullusa = FALSE,
  state.in = "New York",
  county.in = NULL,
  parms = grid_2d(5),
  max_date = NULL,
  lookback_days = 29,
  ...
)

Arguments

src	tibble with cumulative incidence like output of nytimes_state_data()
fullusa	logical(1) if TRUE, use Arima_nation (src should be enriched_jhu_data())
state.in	character(1) state name
county.in	character(1) county name, defaults to NULL, but if supplied, focus on county-level data
parms	two-column data frame with proposed AR order in column 1 and MA order in column 2
max_date	character(1) or lubridate date from which to look back
lookback_days	numeric(1)
...	passed to Arima_by_state or Arima_by_county

Examples

nyd = nytimes_state_data()
mb = min_bic(nyd, state.in="New York")
names(mb)
nytc = nytimes_county_data()
mb2 = min_bic(nytc, state.in="Massachusetts", county.in="Norfolk")
names(mb2)
