ci: Calculation of confidence intervals (based on normal approximation or t-distribution)

Description

Calculation of confidence intervals; based on normal approximation or t-distribution.

Usage

null.effect

A numeric value specifying the effect under the null hypothesis.

Value

List with components

TE

upper

Upper confidence limits

statistic

Test statistic (either z-score or t-score)

p

P-value of text.with null hypothesis TE=0

level

The confidence level required

df

Degrees of freedom (t-distribution)
