The confintr package offers classic and/or bootstrap confidence intervals for the following parameters:
mean,
quantiles incl. median,
proportion,
variance and standard deviation,
IQR and MAD,
skewness and kurtosis,
R-squared and the non-centrality parameter of the F distribution,
Cramér’s V and the non-centrality parameter of the chi-squared distribution,
the odds ratio of a 2x2 table,
Pearson-, Spearman-, Kendall correlation coefficients,
mean, quantile and median differences.
Both one- and two-sided intervals are supported.
Different types of bootstrap intervals are possible through argument boot_type, see vignette.
