Description

[4.0] - 21 October 2019 Added
  • Additional documentation. See: c49fa753201250734f6dbc4bdce6a64959a277cb.
  • Integration test for differential signal fit. See: efcfc40fdf662d5fb0297ed1d02c2f6b538e2485.
Changed
  • Switch emphasis to fitting before normalizing by the number of triggers, including updating default arguments and documentation. See: 17a5d24397c313c3c5a39964e9a8bd471161153e, e04a1f3b1736c8baef41872680bd175f3dadd977, 73f5f0d8dcbf7f86f1742e57279da43fd62faa1f.
  • When reading the RP fit object from YAML, setup the entire fit object. See: 1b38175ae421729a1933bae63bcc6652262927d3.
  • Improve Minuit fit strategy. See: d8dfb49d0599f564597461270b73bb67d1818bdf.
  • Rename _fit to cost_func for clarity - it represents the cost function, not the fit function. And it's sometimes useful to access from outside the object (such as when calculating effective chi squared). See: 3dc750119be1f52f05134b11f24883b2e5c73b07.
  • Make the Minuit verbosity a user settable option. See: 22e67c85b630ef09a3105bcee4587e8d7091b293.
  • Allow a user to skip HESSE when necessary. This should be rare, but it is required at times. See: 98104086ca505a25778c75a0c63053085a836368.
  • Updated the signal differential fit procedure. The inclusive case is just treated as a background only fit. This is required because adding coupling gaussian distributions is not a straightforward process (unlike if they were uncoupled). Consequently, extracting the inclusive width relies on fitting to information already included in the RP fit (included via the differential signal fit components), which means that the covariance of the fit is neglected. Use care when using this fit approach! (A warning is thrown when using it). See: 7ba221d8effcda48d3a5245776aefcb971d7748e.
  • Sample data now acts as if it is the raw correlation rather than scaled by the number of triggers. See: 5c613d2f5d21882fe9d61d6d0067bd602cb74ff2, 9484b457012f6647283e3fc1ebf43a719a0fd7e5, 5c613d2f5d21882fe9d61d6d0067bd602cb74ff2, and 7db8ea4e4201879c609c0cebeb211ea67570e7ba.
  • Improve testing procedure by loading stored fits from YAML rather than defining them by hand in the test file. This makes any future updates much easier. See: 5c613d2f5d21882fe9d61d6d0067bd602cb74ff2.
Fixed
  • Log likelihood fits by updating the underlying pachyderm.fit package. See: 33bdcb41cd0f2dcc6e76f8760b8e5eddd24456dd.
  • Minor typos in code, documentation. See: 150afbba7f065f54895f1bd30409c66df14990b9 and 56af2759823cf2ff027c2b89d7047fdcb2bfc98f.
  • Create output directory when writing if necessary. See: 7ca7f01d12a897907427972c6a9f6402cba6c616.
  • Allow specification of v_{1} values. See: ed037ba57f72dc24257dd6a2dbe1351e85e6c73d and a fix in 63cb49906eabc115f58b6847de756346b61b08c3.
  • Updated typing. See: db79b4134f57ff76727356654489b9a823cb6b67.
  • Integration tests run successfully on TravisCI again. See: 330c3bc6a7f90f1a5e0773c03170a8b27b8cf4ca.
