mv.2way.test {MNM} | R Documentation |
Multivariate tests for testing the null hypothesis that there is no treatment effect in a randomized complete block design using different scores.
mv.2way.test(x, block, treatment, score = c("identity", "sign", "rank"), stand = c("outer", "inner"), method = c("approximation", "permutation"), n.simu = 1000, eps=1.0e-10, n.iter=10000, na.action = na.fail)
x |
a numeric data frame or matrix of response variables. |
block |
a factor with at least two levels. |
treatment |
a factor with at least two levels. |
score |
the score to be used. Possible choices are
identity , sign and rank . |
stand |
the standardization method used. Possible choices are
outer and inner . |
method |
method for the computation of the p-value for the
spatial sign and spatial rank tests. Possible choices are
approximation and permutation . |
n.simu |
number of simulated permutations if method="permutation" . |
eps |
convergence criterion. |
n.iter |
maximum number of iterations. |
na.action |
a function which indicates what should happen when the data contain 'NA's. Default is to fail. |
This implements the tests described in chapter 12 of the MNM book.
A list with class 'htest' containing the following components:
statistic |
the value of the test statistic. |
parameter |
the degrees of freedom for the test statistic or the number of replications in the simulation. |
p.value |
the p-value for the test. |
null.value |
the specified null hypothesis value of the location. |
alternative |
a character string with the value 'two.sided'. |
method |
a character string indicating what type of test was performed. |
data.name |
a character string giving the name of the data set and of the grouping vector. |
