Version 1.7-4

  • New functions

    • bcdcor2 and dcovU2 are faster O(n log n) versions of computing formulas for bcdcor and dcovU, for bivariate (x, y) only.

  • User level changes

    • disco: handle the case when the user argument x is dist with conflicting argument distance=FALSE
    • dcor.t and dcor.ttest: handle the cases when class of argument x or y conflicts with the distance argument
    • Split manual page of dcovU into two files.

  • Internal changes

    • BCDCOR: handle the cases when class of argument x or y conflicts with the distance argument

Version 1.7-2

  • User level changes
    • Provided new dcor.test function, similar to dcov.test but using the distance correlation as the test statistic.
    • Number of replicates R for Monte Carlo and permutation tests now matches the argument of the boot::boot function (no default value, user must specify).
    • If user runs a test with 0 replicates, p-value printed is NA
  • Internal changes
    • energy_init.c added for registering routines

Version 1.7-0

  • Partial Distance Correlation statistics and tests added

    • pdcov, pdcor, pdcov.test, pdcor.test
    • dcovU: unbiased estimator of distance covariance
    • bcdcor: bias corrected distance correlation
    • Ucenter, Dcenter, U_center, D_center: double-centering and U-centering utilities
    • U_product: inner product in U-centered Hilbert space

  • updated NAMESPACE and DESCRIPTION imports, etc.

  • revised package Title and Description in DESCRIPTION

  • package now links to Rcpp

  • mvnorm c code ported to c++ (mvnorm.cpp); corresponding changes in Emvnorm.R

  • syntax for bcdcor: "distance" argument removed, now argument can optionally be a dist object

  • syntax for energy.hclust: first argument must now be a dist object

  • default number of replicates R in tests: for all tests, R now defaults to 0 or R has no default value.

Version 1.6.2

  • inserted GetRNGstate() .. PutRNGState around repl. loop in dcov.c.

Version 1.6.1

  • replace Depends with Imports in DESCRIPTION file

Version 1.6.0

  • 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

Version 1.5.0

  • NAMESPACE: insert UseDynLib; remove zzz.R, .First.Lib()

Version 1.4-0

  • 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.

Version 1.3-0

  • 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).

Version 1.2-0

  • 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"))
