Take a new snapshot of a software origin

If the archived software origin currently browsed is not synchronized with its upstream version (for instance when new commits have been issued), you can explicitly request Software Heritage to take a new snapshot of it.

Use the form below to proceed. Once a request has been submitted and accepted, it will be processed as soon as possible. You can then check its processing state by visiting this dedicated page.

kown problems: in "resampling" the argument lambda is not passed correctly for total.multivariance

Changes in Version 1.2.1
========================

Updates
 * updated references
 * various typos corrected


Changes in Version 1.2.0
========================

New Features
 * 'independence.test' is now also implemented with type "pearson_approx". Providing the fast p-value approximation developed in <arXiv:1808.07280>. For this also the functions 'pearson.qf' (a Gaussian quadratic form estimate based on mean, variance and skewness) and 'pearson.pvalue' (the corresponding p-value estimate based on new moment estimators) are introduced.
 * In "cmd" one can now explicitly specify the use of "isotropic" continuous negative definite functions. This speeds up the calculation for this case by a factor of about 100.

Fixed
 * the option "squared" works now also for multivariance with option "correlation=TRUE".
 * 'multivariances.all' returns NA for 3-multivariance if only two variables are given.

Updates
 * speed up of various functions
 * various typos corrected


Changes in Version 1.1.0
========================
New Features
  * 'm.multivariance' a function to calculate the m-multivariance
  * 'multivariances.all' a function to calculate standard/total/m-multivariance simultaneously
  * 'resample.multivariance' implements the resampling method which can be used to get less conservative tests than the distribution-free methods
  * 'dependence.structure' a function to generate a graphical model of the dependence structure
  * various examples of the use of 'dependence.structure'

Changes
  * The standard output of 'multivariance' is now (distance multivariance squared) scaled by the sample size. Use 'Nscale = FALSE' to get the value without this scaling. The reason for this was twofold: 1. it is now the same setting as for 'total.multivariance'. 2. This is the only value which can (roughly) be interpreted without further calculations.

Updates
  * improved documentation. In particular, it is now cleary stated that the squared values are the standard output of 'multivariance' and 'total.multivariance'
  * some speed up


Changes in Version 1.0.5 2017-11-01
===================================
Details
  * Initial public release
