For incremental values the DeltaLiveStat provides an easy to use helper.\n\nUsage:\n\n\tfrom livestat import LiveStat,DeltaLiveStat\n\n\tx = LiveStat(\"optionalname\")\n\tx.append(10)\n\tx.append(20)\n\tprint x # count is 2\n\n\tx = DeltaLiveStat(\"dt\")\n\tx.append(10)\n\tx.append(20)\n\tprint x # count is 1 containing the difference\n\n\t#also from array\n\tx.extend([10,20,30,40,50])\n\nExtra Features: \n\t\n\t# the LiveStat objects can be combined for example when performing over different data Windows or in a multiprocessing environment\n\tx.merge(y) # now x contains the merge of the statistics\n\n\t# the LiveStat object can be multipled by scalar or translated, for the objective of performing some unit transformation. All the measures are transformed appropriately\n\tx + 5\n\tx * 5\n\nIn progress:\n- numpy support\n- normality test\n\nPackage Repository\n==================\nThis project is maintained here: https://github.com/sankazim/pylivestat\n\n\nRelated\n===========\nThe faststat package is similar:\n\thttps://pypi.python.org/pypi/faststat/\n\thttps://github.com/doublereedkurt/faststat/", "description_content_type": null, "docs_url": null, "download_url": "UNKNOWN", "downloads": { "last_day": -1, "last_month": -1, "last_week": -1 }, "home_page": "UNKNOWN", "keywords": "statistics kurtosis skewness live variance", "license": "BSD", "maintainer": null, "maintainer_email": null, "name": "livestat", "package_url": "https://pypi.org/project/livestat/", "platform": "UNKNOWN", "project_url": "https://pypi.org/project/livestat/", "project_urls": { "Download": "UNKNOWN", "Homepage": "UNKNOWN" }, "release_url": "https://pypi.org/project/livestat/0.1.1/", "requires_dist": null, "requires_python": null, "summary": "Computing descriptive statistics over streaming data", "version": "0.1.1" }, "last_serial": 959318, "releases": { "0.1": [ { "comment_text": "", "digests": { "md5": "a2bc2cbed29d9624c0da3f7d8f5299e7", "sha256": "fec365fafb942ac48e481fd158d33f4792aea75c0e4061aef3a7731f2a001510" }, "downloads": -1, "filename": "livestat-0.1.macosx-10.9-intel.exe", "has_sig": false, "md5_digest": "a2bc2cbed29d9624c0da3f7d8f5299e7", "packagetype": "bdist_wininst", "python_version": "any", "requires_python": null, "size": 72398, "upload_time": "2014-01-03T09:33:18", "url": "https://files.pythonhosted.org/packages/1c/07/b3eb5bcec0f8723fcd84f2495516d0ba2b5fc69296739ead3dc13bd0de83/livestat-0.1.macosx-10.9-intel.exe" }, { "comment_text": "", "digests": { "md5": "48f7ba07cbee9f8d6370e02a15aa047d", "sha256": "0354011ae4be148e6a445af2eb08741937fd6c0c87aae5bdfa17fc55efa4bc9c" }, "downloads": -1, "filename": "livestat-0.1.tar.gz", "has_sig": false, "md5_digest": "48f7ba07cbee9f8d6370e02a15aa047d", "packagetype": "sdist", "python_version": "source", "requires_python": null, "size": 8087, "upload_time": "2014-01-03T09:33:13", "url": "https://files.pythonhosted.org/packages/69/36/44edf406aa25f6dbc4cefbd5c1c7381da548ed72546403f92509e9ef0f5d/livestat-0.1.tar.gz" } ], "0.1.1": [ { "comment_text": "", "digests": { "md5": "a6d0e58f3397276cd3d64ce6a11dd300", "sha256": "a83b66305007d1ad49b885551e49d916a72728fbdeaad526a6e263148a1cfa2c" }, "downloads": -1, "filename": "livestat-0.1.1.macosx-10.9-intel.exe", "has_sig": false, "md5_digest": "a6d0e58f3397276cd3d64ce6a11dd300", "packagetype": "bdist_wininst", "python_version": "any", "requires_python": null, "size": 72589, "upload_time": "2014-01-03T09:35:12", "url": "https://files.pythonhosted.org/packages/5d/e2/9b26d93cf94335f29e27eeea601475f0c9deec71cb354820844c5dd29051/livestat-0.1.1.macosx-10.9-intel.exe" }, { "comment_text": "", "digests": { "md5": "fca05c470ac8ac89ac015e4132e80816", "sha256": "377737ba446370d7cf51f08fdd2aff1cc75e96973c8eec264af16f9b68b898a5" }, "downloads": -1, "filename": "livestat-0.1.1.tar.gz", "has_sig": false, "md5_digest": "fca05c470ac8ac89ac015e4132e80816", "packagetype": "sdist", "python_version": "source", "requires_python": null, "size": 8132, "upload_time": "2014-01-03T09:35:08", "url": "https://files.pythonhosted.org/packages/6d/4e/5a26c037ef8a9f81108d50b4c6b85f8dd50edb1240df4218d0cdd06b8fdc/livestat-0.1.1.tar.gz" } ] }, "urls": [ { "comment_text": "", "digests": { "md5": "a6d0e58f3397276cd3d64ce6a11dd300", "sha256": "a83b66305007d1ad49b885551e49d916a72728fbdeaad526a6e263148a1cfa2c" }, "downloads": -1, "filename": "livestat-0.1.1.macosx-10.9-intel.exe", "has_sig": false, "md5_digest": "a6d0e58f3397276cd3d64ce6a11dd300", "packagetype": "bdist_wininst", "python_version": "any", "requires_python": null, "size": 72589, "upload_time": "2014-01-03T09:35:12", "url": "https://files.pythonhosted.org/packages/5d/e2/9b26d93cf94335f29e27eeea601475f0c9deec71cb354820844c5dd29051/livestat-0.1.1.macosx-10.9-intel.exe" }, { "comment_text": "", "digests": { "md5": "fca05c470ac8ac89ac015e4132e80816", "sha256": "377737ba446370d7cf51f08fdd2aff1cc75e96973c8eec264af16f9b68b898a5" }, "downloads": -1, "filename": "livestat-0.1.1.tar.gz", "has_sig": false, "md5_digest": "fca05c470ac8ac89ac015e4132e80816", "packagetype": "sdist", "python_version": "source", "requires_python": null, "size": 8132, "upload_time": "2014-01-03T09:35:08", "url": "https://files.pythonhosted.org/packages/6d/4e/5a26c037ef8a9f81108d50b4c6b85f8dd50edb1240df4218d0cdd06b8fdc/livestat-0.1.1.tar.gz" } ] }
