    • NAMESPACE added.
      • -
    • (dcov.c, Eindep.c) Unused N was removed.
      • -
    • (dcov.c) In case dcov=0, bypass the unnecessary loop that generates replicates (in dCOVtest and dCovTest). In this case dcor=0 and test is not significant. (dcov=0 if one of the samples is constant.)
      • -
    • (Eqdist.R) in eqdist.e and eqdist.etest, method=“disco” is replaced by two options: “discoB” (between sample components) and “discoF” (disco F ratio).

    • (energy.c) In ksampleEtest the pval computation changed from ek/B to (ek+1)/(B+1) as it should be for a permutation test, and unneeded int* n removed.

    energy 1.3-02011-02-15

    -

    • In distance correlation, distance covariance functions (dcov, dcor, DCOR) and dcov.test, arguments x and y can now optionally be distance objects (result of dist function or as.dist). Matrices x and y will always be treated as data.

      • -

    • Functions in dcov.c and utilities.c were modified to support arguments that are distances rather than data. In utilities.c the index_distance function changed. In dcov.c there are many changes. Most importantly for the exported objects, there is now an extra required parameter in the dims argument passed from R. In dCOVtest dims must be a vector c(n, p, q, dst, R) where n is sample size, p and q are dimensions of x and y, dst is logical (TRUE if distances) and R is number of replicates. For dCOV dims must be c(n, p, q, dst).

    -
    • disco (distance components) added for one-way layout.
      • -
    • A method argument was added to ksample.e, eqdist.e, and eqdist.etest, method = c(“original”, “disco”).
      • -
    • A method argument was added to edist, which summarizes cluster distances in a table: method = c(“cluster”,“discoB”,“discoF”))

    • implementation of high-dim distance correlation t-test introduced in JMVA Volume 117, pp. 193-213 (2013).
      • +
    • new functions dcor.t, dcor.ttest in dcorT.R
      • +
    • minor changes to tidy other code in dcov.R
      • +
    • removed unused internal function .dcov.test

    +
    • NAMESPACE added.
      • +
    • (dcov.c, Eindep.c) Unused N was removed.
      • +
    • (dcov.c) In case dcov=0, bypass the unnecessary loop that generates replicates (in dCOVtest and dCovTest). In this case dcor=0 and test is not significant. (dcov=0 if one of the samples is constant.)
      • +
    • (Eqdist.R) in eqdist.e and eqdist.etest, method=“disco” is replaced by two options: “discoB” (between sample components) and “discoF” (disco F ratio).
      • +
    • (disco.R) Added disco.between and internal functions that compute the disco between-sample component and corresponding test.
      • +
    • (utilities.c) In permute function replaced rand_unif with runif.
      • +
    • (energy.c) In ksampleEtest the pval computation changed from ek/B to (ek+1)/(B+1) as it should be for a permutation test, and unneeded int* n removed.

    • In distance correlation, distance covariance functions (dcov, dcor, DCOR) and dcov.test, arguments x and y can now optionally be distance objects (result of dist function or as.dist). Matrices x and y will always be treated as data.

      • +

    • Functions in dcov.c and utilities.c were modified to support arguments that are distances rather than data. In utilities.c the index_distance function changed. In dcov.c there are many changes. Most importantly for the exported objects, there is now an extra required parameter in the dims argument passed from R. In dCOVtest dims must be a vector c(n, p, q, dst, R) where n is sample size, p and q are dimensions of x and y, dst is logical (TRUE if distances) and R is number of replicates. For dCOV dims must be c(n, p, q, dst).

    • disco (distance components) added for one-way layout.
      • +
    • A method argument was added to ksample.e, eqdist.e, and eqdist.etest, method = c(“original”, “disco”).
      • +
    • A method argument was added to edist, which summarizes cluster distances in a table: method = c(“cluster”,“discoB”,“discoF”))
