ridge multi target with individual penalties written. To be tested
old tests passing
new multiple target tests added, functionality confined to direct usage of ridge_regression function
Ridge estimator works with individual penalties
test for ridge estimator
ridge doc string
ValueError for wrong shaped input instead of assertion failure, in order for sklearn/tests/test_common.py, line 238 to pass
docstring in Ridge estimator
added individual penalties function for all other solvers. Tests passing for all of them
always make alpha into an array
updated tests
tests passing
removed elaborate testing in ridge.fit, not necessary anymore
Test exception is raison when number of targets and penalties don't
match.
Simplify ridge solvers (ongoing work).
