Flag significant changes in impact estimates

Source: R/fn_impact_diagnostics.R
flag_large_diffs.Rd

Calculates and flags whether the difference in impact estimates between touchstones is greater than expected. A row is flagged if the difference is greater than threshold \(\times\) the inter-quartile range for cases where the IQR is greater than zero.

Usage

flag_large_diffs(
  changes_list,
  iqr_df,
  variable = c("deaths_averted", "dalys_averted"),
  group_cols = c("country", "vaccine", "activity_type"),
  threshold = 100,
  touchstone_old = DEF_TOUCHSTONE_OLD_OLD,
  touchstone_new = DEF_TOUCHSTONE_NEW
)

Arguments

changes_list

A list of data.frames with one element per variable of interest (see variable). Usually generated using generate_diffs().

iqr_df

A data.frame of inter-quartile differences generated using gen_national_iqr().

variable

A string specifying the variable of interest. Must be one of "deaths_averted" or "dalys_averted", and must be present as a name and element of changes_list.

group_cols

A character vector of grouping columns. Defaults to "country", "vaccine", "activity_type".

threshold

A single numeric value for the IQR multiplier. Defaults to 100.

touchstone_old

The previous touchstone identifier. Defaults to DEF_TOUCHSTONE_OLD_OLD.

touchstone_new

The new touchstone identifier. Defaults to DEF_TOUCHSTONE_NEW.

Value

A filtered data.frame of differences in impact estimates flagged as too large. Rows with differences within tolerance are removed.
