Confidence Interval for a Difference of Binomials

description

Several confidence intervals for the difference between proportions are available, but they can produce markedly different results. Traditional approaches, such as the Wald interval do not perform well unless the sample size is large. Better intervals are available. These include the Agresti/Caffo method (2000), Newcombe Score method (1998) and more computing intensive ones as by Miettinen and Nurminen (1985) or Mee (1984). The latter ones are favoured by Newcombe (when forced to choose between a rock and a hard place).

Calculate Generalized Log Odds Ratios for Frequency Tables

description

Computes (log) odds ratios and their asymptotic variance covariance matrix for R x C (x strata) tables. Odds ratios are calculated for two array dimensions, separately for each level of all stratifying dimensions. See Friendly et al. (2011) for a sketch of a general theory.

Calculate Generalized Log Odds for Frequency Tables

description

Computes (log) odds and their asymptotic variance covariance matrix for R (by strata) tables. Odds are calculated for pairs of levels of one array dimension (typically a response or focal variable) separately for each level of all stratifying dimensions. See Friendly et al. (2011) for a sketch of a general theory.
