Description Usage Arguments Examples
Inference: Based on generalised inference principles.
1 2 3 | metagenGeneralised(y, d, x, sgnf, s = NULL, n,
method = list("univariate", "multivariate"),
adjusted = FALSE)
|
y |
k-vector of responses. |
d |
k-vector of heteroscedasticities. |
x |
design k-p-matrix. |
sgnf |
vector of significance levels |
s |
k-vector of study responses. No need to provide this, when 'adjusted==FALSE'. Default is NULL. |
n |
draws from the pivotal distribution. |
method |
Default is 'list("univariate", "multivariate")'. |
adjusted |
TRUE or FALSE. Default is FALSE. |
