leave1out.rma.mh {metafor} | R Documentation |
The functions leave1out.rma.mh
and leave1out.rma.peto
repeatedly fit the specified model, leaving out one observation (i.e., 2x2 table) at a time.
## S3 method for class 'rma.mh': leave1out(x, digits=x$digits, transf=FALSE, ...) ## S3 method for class 'rma.peto': leave1out(x, digits=x$digits, transf=FALSE, ...)
x |
an object of class "rma.mh" or "rma.peto" . |
digits |
an integer specifying the number of decimal places to which the printed results should be rounded (the default is to take the value from the object). |
transf |
logical indicating whether odds ratios or risk ratios (and the corresponding confidence interval bounds) should be given in the transformed (meaning: raw) units or in terms of log units (the default). |
... |
other arguments. |
An object of class "list.rma"
. The object is a list containing the following components:
estimate |
estimated coefficients of the model. |
se |
standard errors of the coefficients. NA if transf=TRUE . |
zval |
test statistics of the coefficients. |
pval |
p-values for the test statistics. |
ci.lb |
lower bounds of the confidence intervals for the coefficients. |
ci.ub |
upper bounds of the confidence intervals for the coefficients. |
Q |
test statistics for the tests of heterogeneity. |
Qp |
p-values for the tests of heterogeneity. |
The "list.rma"
object is formated and printed with print.list.rma
.
