4e2b2c66c2 * Added wpylib.math.stats.jackknife1, initial implementation of delete-one 
jackknife resampling method.

  This module also contains a hack for weighted average
  (warning: the theory is not established yet, at least I have not seen
  it).

ed1242dc66 * Added "lazy string printout" which will speed up errorbar algebra--i.e. 
we only need to evaluate the string representation when
  the string printout isrequired.

80961ed2bd * Added test7 and test8 for param_flat module. 
- test7 tests active parameters which can work OK if the search dicts are
    flatten.
  - test8 tests the _flatten_() method.
 2013-04-17 17:26:48 -04:00
Wirawan Purwanto
b326937d80 * Parameters: Now correctly implements _flatten_() method and flag. 
- The _flatten_() method should recursively flatten the parameter
    search space into a single dict.
  - The _flatten_ flag will flatten the input dicts and keyword-based
    parameter (in the __init__() method only) in the expected order of
    priority (where the first found keyword is the most overriding one)
    into a single search dict.
 2013-04-16 14:06:26 -04:00
Wirawan Purwanto
8d32c2c067 * Parameters: if _flatten_ is enabled, must flatten in reverse order to 
give the firstly mentioned dict the priority.
