FunnelPlotR (version 0.6.0)

calculate_limits: Overdispersion-adjusted funnel limit calculation

Description

Add 95 distribution

Usage

calculate_limits(
  df_ci = df_ci,
  data_type = "SR",
  sr_method = "SHMI",
  multiplier = 1,
  tau2 = 0,
  target = target,
  draw_adjusted = draw_adjusted
)

Value

A data.frame of with appended OD limits

Arguments

df_ci

Aggregated model input data

data_type

Type of data for adjustment and plotting: Indirectly Standardised ratio ("SR"), proportion ("PR") , or ratio of counts ("RC").

sr_method

Adjustment method for standardised ratios, can take the value "SHMI" or "CQC". "SHMI" is default.

multiplier

Multiplier to adjust limits if reporting by a multiplier , e.g. per 1000.

tau2

A 'between' standard deviation to add to the within standard deviation, S, to inflate limits.

target

The centre line of the plot. Mean for non-SRs or 1 for SR
