This basically boils down to a limit and it makes sense. Consider the combinations of numbers between 0 and 10 and count the various differences you can make. For example, there is one combination with a difference of 9 — (0, 9). There are 5 with a difference of 5: [0, 5], [1, 6], [2, … Read more
To the best of my knowledge, there is none. Writing one is pretty straightforward, though. The following gives you the constant alpha and slope beta for y = Alpha + Beta * x + epsilon: — test data (GroupIDs 1, 2 normal regressions, 3, 4 = no variance) WITH some_table(GroupID, x, y) AS ( SELECT … Read more
If you know in advance that you’re going to want to multiple samples without overlaps, easiest is to do random.shuffle() on list(range(100)) (Python 3 – can skip the list() in Python 2), then peel off slices as needed. s = list(range(100)) random.shuffle(s) first_sample = s[-10:] del s[-10:] second_sample = s[-10:] del s[-10:] # etc Else … Read more
Recall literally is how many of the true positives were recalled (found), i.e. how many of the correct hits were also found. Precision (your formula is incorrect) is how many of the returned hits were true positive i.e. how many of the found were correct hits.
I’m not sure completely understand, but it appears you are trying to re-index each axis of the array based on sorts of the dendrogram indicies. I guess that assumes there is some comparative logic in each branch delineation. If this is the case then would this work(?): >>> x_idxs = [(0,1,0,0),(0,1,1,1),(0,1,1),(0,0,1),(1,1,1,1),(0,0,0,0)] >>> y_idxs = [(1,1),(0,1),(1,0),(0,0)] … Read more
