fecrtCI {eggCounts}R Documentation

Compute standard FECRT according to WAAVP guidelines

Description

Computes the standard Faecal Egg Count Reduction Test together with approximate confidence interval according to the WAAVP guidelines (Coles et al., 1992, 2006). The function also returns bootstrap confidence intervals.

Usage

fecrtCI(epg1, epg2, paired = FALSE, alpha = 0.05, R = 1999)

Arguments

epg1

numeric vector. Faecal egg counts in untreated animals.

epg2

numeric vector. Faecal egg counts in treated animals.

paired

logical. If TRUE, indicates samples are paired. Otherwise samples are unpaired.

alpha

numeric. Confidence level of the interval.

R

numeric. Number of bootstrap replicates.

Value

A list with

estimate

estimated percentage reduction in mean epg

bootCI

bootstrap confidence interval

approxCI

approximate confidence interval
