loo function

Leave-one-out method for precision of treatment hierarchy (POTH) metric

## S3 method for class 'poth'
loo(x, ...)

loo(x, ...)

## S3 method for class 'loo.poth'
print(x, digits = 3, legend = TRUE, ...)

Arguments

• x: An R object of class poth.
• ...: Additional arguments.
• digits: Minimal number of significant digits, see print.default.
• legend: A logical indicating whether a legend should be printed.

Returns

A data frame with additional class loo.poth and the following variables: - trt: Treatment names.

• rank: Treatment rank (global).

• score: Ranking metric (global).

• poth_loo: Leave-one-out POTH.

• resid: Residuals (global POTH minus leave-one-out POTH.

• ratio: Ratio of residual devided by absolute sum of residuals.

Examples

library("netmeta")
data(smokingcessation)
p1 <- pairwise(list(treat1, treat2, treat3),
  event = list(event1, event2, event3), n = list(n1, n2, n3),
  data = smokingcessation, sm = "OR")
net1 <- netmeta(p1, random = FALSE)

# Leave-one-out method
loo1 <- loo(poth(net1))
