In dmorrison01/CSICalc: Cross-Sectional Incidence Estimate and CI Calculator

Calculate the error in matching a specified confidence interval with a Gamma distribution prior.

Description

Calculate the error in matching a specified confidence interval with a Gamma distribution prior.

Usage

sum_squares(
  shape,
  lower_CI,
  upper_CI,
  mean,
  confidence_level = 0.95,
  alpha = (1 - confidence_level)/2
)

Arguments

shape	The shape ("gamma") parameter of a Gamma distribution
lower_CI	The lower confidence limit that we are trying to match
upper_CI	The upper confidence limit that we are trying to match
mean	The mean of the Gamma distribution (= shape * scale)
confidence_level	The confidence level of the confidence interval (1 - alpha)
alpha	= 1 - 'confidence_level'

Value

The sum of relative squared errors between the confidence limits and the quantiles of the fitted distribution.
