Class "uvmeta". Result of a univariate meta-analysis.

This class encapsulates results of a univariate meta-analysis.

Objects from the Class

Objects can be created by calls of the form uvmeta.

Slots

call:: (language) The call to uvmeta.
data:: (data frame) The data used for the meta-analysis.
results:: (data frame) Contains the pooled effect size (mu), the between-study variability (tausq), Cochran's Q statistic (Q) and Higgins' and Thompson's I square statistic (Isq). For each estimate, error variances are provided with predefined confidence (method="MOM") or credibility (method="bayes") intervals.
model:: (character) The meta-analysis model used.
method:: (character) The estimator used.
na.action:: (character) Information from the action which was applied to object if NAs were handled specially, or NULL.
df:: (numeric) Degrees of freedom.
numstudies:: (numeric) The amount of studies used in the meta-analysis.
pred.int:: (data frame) A prediction interval, predicting in what range future effect sizes will fall given what has already been observed (based on a Student's t-distribution, cfr. Riley 2011)
formula:: (character) If a formula was specified, a character vector giving the formula and parameter specifications.

Methods

print: signature(object = "uvmeta"): Print object summary.
forest: signature(object = "uvmeta"): Plot a forest plot with the summary estimate.
summary: signature(object = "uvmeta"): Generate object summary.

Examples

#Extract effect size and error variance
r <- Collins$logOR
vars <- Collins$SE**2

#Frequentist random-effects meta-analysis
fit1 <- uvmeta(r,vars)
