class skbio.stats.gradient.GradientANOVA(coords, prop_expl, metadata_map, trajectory_categories=None, sort_category=None, axes=3, weighted=False)[source]

Base class for the Trajectory algorithms

Parameters
• coords (pandas.DataFrame) – The coordinates for each sample id

• prop_expl (array like) – The numpy 1-D array with the proportion explained by each axis in coords

• trajectory_categories (list of str, optional) – A list of metadata categories to use to create the trajectories. If None is passed, the trajectories for all metadata categories are computed. Default: None, compute all of them

• sort_category (str, optional) – The metadata category to use to sort the trajectories. Default: None

• axes (int, optional) – The number of axes to account while doing the trajectory specific calculations. Pass 0 to compute all of them. Default: 3

• weighted (bool, optional) – If true, the output is weighted by the space between samples in the sort_category column

Raises

ValueError – If any category of trajectory_categories is not present in metadata_map If sort_category is not present in metadata_map If axes is not between 0 and the maximum number of axes available If weighted is True and no sort_category is provided If weighted is True and the values under sort_category are not numerical If coords and metadata_map does not have samples in common

Built-ins

 __hash__ Return hash(self).

Methods

 Compute the trajectories for each group in each category and run
