After the release, future breaking changes will occur less frequently and with more notice. Please raise issues as needed.**\n\n`causaldag` is common wrapper for the following packages:\n* https://github.com/uhlerlab/graphical_models\n* https://github.com/uhlerlab/conditional_independence\n* https://github.com/uhlerlab/graphical_model_learning\n\nInstalling and importing `causaldag` should be sufficient for most use cases.\n\nCausalDAG is a Python package for the creation, manipulation, and learning\nof Causal DAGs. CausalDAG requires Python 3.5+\n\n### Install\nInstall the latest version of CausalDAG:\n```\n$ pip3 install causaldag\n```\n\n### Cite\nYou may use the following bibtex for citing `causaldag`:\n```\n@manual{squires2018causaldag,\n  title={{\\texttt{causaldag}: creation, manipulation, and learning of causal models}},\n  author={{Chandler Squires}},\n  year={2018},\n  url={https://github.com/uhlerlab/causaldag},\n}\n```\n\nOr the following text:\n\n> Chandler Squires. _causaldag: creation, manipulation, and learning of causal models_, 2018. URL https://github.com/uhlerlab/causaldag\n\n### Documentation\nDocumentation for each subpackage is available at:\n* graphical_models: https://graphical-models.readthedocs.io/en/latest/\n* graphical_model_learning: https://graphical-model-learning.readthedocs.io/en/latest/\n* conditional_independence: https://conditional-independence.readthedocs.io/en/latest/\n\nExamples for specific algorithms can be found at https://uhlerlab.github.io/causaldag/\n\n### Simple Example\nFind the CPDAG (complete partially directed acyclic graph,\nAKA the *essential graph*) corresponding to a DAG:\n```\n>>> from causaldag import rand, partial_correlation_suffstat, partial_correlation_test, MemoizedCI_Tester, gsp\n>>> import numpy as np\n>>> np.random.seed(12312)\n>>> nnodes = 5\n>>> nodes = set(range(nnodes))\n>>> dag = rand.directed_erdos(nnodes, .5)\n>>> gdag = rand.rand_weights(dag)\n>>> samples = gdag.sample(100)\n>>> suffstat = partial_correlation_suffstat(samples)\n>>> ci_tester = MemoizedCI_Tester(partial_correlation_test, suffstat, alpha=1e-3)\n>>> est_dag = gsp(nodes, ci_tester)\n>>> dag.shd_skeleton(est_dag)\n```\n\n### License\n\nReleased under the 3-Clause BSD license (see LICENSE.txt):\n```\nCopyright (C) 2018\nChandler Squires <csquires@mit.edu>\n```\n"

For applications of DCI to larger gene expression datasets, we recommend running DCI on a subset of genes (e.g. differentially expressed genes). For most robust results, we recommend using DCI with stability selection [3].\n\n\n### Algorithm details\nDCI algorithm consists of three main steps:\n1. Initialization with a difference undirected graph.\n2. Estimation of the skeleton of the difference causal graph.\n3. Orienting edges in the difference causal graph.\n\n### References\n\n[1] Belyaeva, A., Squires, C., & Uhler, C. (2020). DCI: Learning Causal Differences between Gene Regulatory Networks.

DCI expects two matrices of size \\\\(n_1 \\times p\\\\) and \\\\(n_2 \\times p\\\\), where \\\\(n_1\\\\) and \\\\(n_2\\\\) are the number of samples in each dataset and \\\\(p\\\\) corresponds to the number of genes. We recommend transforming RNA-seq counts with \\\\(\\log(x + 1)\\\\) such that the distribution of each gene is approximately Gaussian. \n\n\n```python\npath_in = 'causaldag/datasets/data/'\ngene_exp_diff_1 = pd.read_csv(os.path.join(path_in, 'apoptosis_1.csv'), index_col=0)\ngene_exp_diff_2 = pd.read_csv(os.path.join(path_in, 'apoptosis_2.csv'), index_col=0)\ngene_names = gene_exp_diff_1.columns.values\n```\n\n\n```python\ngene_exp_diff_1.shape, gene_exp_diff_2.shape\n```\n\n\n\n\n    ((83, 10), (168, 10))\n\n\n\n\n```python\ngene_names\n```\n\n\n\n\n    array(['TP53', 'TNFSF10', 'IL1R1', 'PRKAR2B', 'FAS', 'ENDOG', 'CSF2RB',\n           'AIFM1', 'BIRC3', 'PIK3R1'], dtype=object)\n\n\n\n<a id=\"pre\"></a>\n### Data preprocessing\nPrior to running DCI, the data should be at least mean cenetered (along with any other transformations).\n\n\n```python\nscaler = StandardScaler(with_std=False)\nX1 = scaler.fit_transform(gene_exp_diff_1.values)\nX2 = scaler.fit_transform(gene_exp_diff_2.values)\n```\n\n<a id=\"DCI\"></a>\n### Running DCI\nRun DCI on the two datasets with default parameters or by specifying your own hyperparameters.\n\n\n```python\nd_dag = dci(X1, X2, alpha_ug = 0.001, alpha_skeleton=0.5, alpha_orient=0.001, max_set_size=3, verbose=1)\n```\n\n    Running KLIEP to get difference undirected graph...\n    Maximum iteration reached\n    Difference undirected graph:  [(0, 2), (0, 4), (0, 8), (0, 9), (1, 3), (1, 4), (1, 5), (1, 6), (1, 7), (1, 8), (1, 9), (2, 3), (2, 4), (2, 6), (2, 9), (3, 4), (3, 5), (3, 6), (3, 7), (3, 8), (3, 9), (4, 5), (4, 6), (4, 7), (4, 8), (4, 9), (5, 6), (5, 8), (5, 9), (6, 7), (6, 8), (7, 8), (7, 9), (8, 9)]\n    DCI skeleton estimation...\n    Removing edge 0-2 since p-value=0.82759 > alpha=0.50000\n    Removing edge 0-4 since p-value=0.56434 < alpha=0.50000\n    Removing edge 0-8 since p-value=0.57503 > alpha=0.50000\n    Removing edge 0-9 since p-value=0.95151 > alpha=0.50000\n    Removing edge 1-3 since p-value=0.55181 > alpha=0.50000\n    Removing edge 1-4 since p-value=0.77913 > alpha=0.50000\n    Removing edge 1-6 since p-value=0.64699 < alpha=0.50000\n    Removing edge 1-7 since p-value=0.51028 < alpha=0.50000\n    Removing edge 1-8 since p-value=0.62069 < alpha=0.50000\n    Removing edge 1-9 since p-value=0.84008 > alpha=0.50000\n    Removing edge 2-3 since p-value=0.59656 < alpha=0.50000\n    Removing edge 2-4 since p-value=0.54203 < alpha=0.50000\n    Removing edge 2-9 since p-value=0.70060 > alpha=0.50000\n    Removing edge 3-4 since p-value=0.97752 > alpha=0.50000\n    Removing edge 3-5 since p-value=0.79810 > alpha=0.50000\n    Removing edge 3-6 since p-value=0.72510 > alpha=0.50000\n    Removing edge 3-7 since p-value=0.54904 < alpha=0.50000\n    Removing edge 3-9 since p-value=0.71211 < alpha=0.50000\n    Removing edge 4-5 since p-value=0.70280 > alpha=0.50000\n    Removing edge 4-6 since p-value=0.65148 > alpha=0.50000\n    Removing edge 4-7 since p-value=0.50519 > alpha=0.50000\n    Removing edge 4-8 since p-value=0.96052 > alpha=0.50000\n    Removing edge 4-9 since p-value=0.70320 < alpha=0.50000\n    Removing edge 5-6 since p-value=0.64493 < alpha=0.50000\n    Removing edge 5-8 since p-value=0.66995 < alpha=0.50000\n    Removing edge 6-7 since p-value=0.51135 < alpha=0.50000\n    Removing edge 6-8 since p-value=0.63820 > alpha=0.50000\n    Removing edge 7-9 since p-value=0.61907 > alpha=0.50000\n    Removing edge 8-9 since p-value=0.67268 > alpha=0.50000\n    DCI edge orientation...\n    Oriented (5, 9) as (5, 9) since p-value=0.00100 > alpha=0.00100\n    Oriented (1, 5) as (5, 1) since p-value=0.00100 > alpha=0.00100\n    Oriented (3, 8) as (3, 8) since p-value=0.01109 > alpha=0.00100\n    Oriented (2, 6) as (6, 2) since p-value=0.00288 > alpha=0.00100\n    Oriented (7, 8) as (7, 8) since p-value=0.23781 > alpha=0.00100\n\n\n<a id=\"graph\"></a>\n### Visualizing causal graphs\nPlot directed and undirected edges corresponding to the estimated difference causal graph.\n\n\n```python\ndef visualize_ddag(d_dag, gene_names):\n    \"\"\"\n    Plots causal graph.\n\n    Parameters\n    ----------\n    d_dag: array, shape = [n_features, n_features]\n        Adjacency matrix corresponding to partially directed acyclic graph (can contain both directed and undirected edges.)\n    gene_names: array, shape = [n_features,]\n        Names of genes corresponding to each node in the d_dag.\n    \"\"\"\n    #

There are three main hyperparameters corresponding to the three steps of the DCI algorithm:\n1. List of hyperparameters for L1 regularization of the KLIEP algorithm, which computes the difference undirected graph (alpha_ug_grid).\n2. List of significance levels for hypothesis testing to determine the skeleton of the difference causal graph (alpha_skeleton_grid).\n3. List of significance levels for hypothesis testing to orient edges of the difference causal graph (alpha_orient_grid).\n\nTo speed up computation, we recommend to run DCI with stability selection in parallel.\n\n\n```python\nd_dag_stable, stability_scores = dci_stability_selection(X1, X2, alpha_ug_grid = [0.001, 0.01], alpha_skeleton_grid = [0.1, 0.5], alpha_orient_grid = [0.001, 0.01], edge_threshold=0, max_set_size=3, n_jobs = 10, n_bootstrap_iterations=50, random_state=42, verbose=1)\n```\n\n```python\nvisualize_ddag(d_dag_stable, gene_names)\n```\n\n\n![png](images/DCI_18_0.png)\n\n[back](./dci.html)"
