calculate_confidence_intervals: Confidence interval from estimate and standard error

In fb4package: 'Fish Bioenergetics 4.0' Model Implementation with High-Performance 'TMB' Backend

Confidence interval from estimate and standard error

Description

Computes a symmetric confidence interval given a point estimate and its standard error. Returns NA bounds when either input is NA.

Usage

calculate_confidence_intervals(
  estimate,
  se,
  confidence_level = 0.95,
  method = "normal"
)

Arguments

estimate	Numeric point estimate (scalar or vector)
se	Standard error of the estimate
confidence_level	Confidence level in (0, 1), default 0.95
method	"normal" (default) for symmetric normal-theory interval; "log-normal" for a delta-method interval on the log scale (requires estimate > 0)

Value

Named list with ci_lower, ci_upper, method, and confidence_level

Examples

calculate_confidence_intervals(0.5, 0.05)
calculate_confidence_intervals(0.5, 0.05, confidence_level = 0.99)
calculate_confidence_intervals(NA, 0.05)
