assocSignTest {BiCausality} | R Documentation |
indpFunc function
Description
This function provides association signs (positive/negative association) inference between i and j. If there is a positive association, it implies i and j trend to have a similar value. For a negative association, however, i and j trend to have an opposite value.
Usage
assocSignTest(mat, i, j, z = c(), alpha = 0.05, IndpThs = 0.05, nboot = 100)
Arguments
mat |
is a matrix n by d where n is a number of transactions or samples and d is a number of dimensions. |
i |
is an ith dimension in |
j |
is an jth dimension in |
z |
is a conditioning d-dimensional vector on |
alpha |
is a significance threshold for hypothesis tests (Mann Whitney) that deploys for testing degrees of dependency, association direction, and causal direction. The default is 0.5. |
IndpThs |
is a threshold for the degree of dependency. In the independence test, to claim that any variables are dependent, the dependency degree must greater than this value significantly. The default is 0.05. |
nboot |
is a number of bootstrap replicates for bootstrapping deployed to infer confidence intervals and distributions for hypothesis tests. The default is 100. |
Value
This function returns results of inference of association signs (positive/negative association) between i and j.
bmean |
A mean of sign dependency degrees between variables i and j. |
confInv |
An |
testRes |
A Mann-Whitney hypothesis test result for an independence test between variables i and j. The null hypothesis is that the distributions of dependency degrees of i,j differ by a location shift of |
