Discrepancies between final result and edge-probabilities in bootsrapping. Which is true?

[yasu-sh]

Hi, developers,

I have concerned if the result is correct or not in bootstrapping. There are 3 discrepancies in the edge list. I have tried to understand the json file structure as a hint. But too difficult for me.

Could you solve this issue? This result would be the same from the version around 1.2.1(I experienced in past).

Bootstrappiung: Number of searches that didn't return a graph = 0

Graph Edges:

1. B o-> D [B o-> D]:1.0000;
2. B o-o S [B o-o S]:1.0000;
3. E --> D [D --> E]:1.0000;
4. E --> X [E --> X]:1.0000;
5. L o-> E [E o-> L]:1.0000;
6. L o-o S [L o-o S]:1.0000;
7. T o-> E [E o-> T]:1.0000;

I compared the same dataset and setting at TETRAD-GUI ver. 7.1.2-2

data: asia.csv (created from bnlearn, data(asia)) causal-cmd version 1.4.1, downloaded from https://s01.oss.sonatype.org/content/repositories/releases/io/github/cmu-phil/causal-cmd/1.4.1/

java -version openjdk version "1.8.0_342" OpenJDK Runtime Environment Corretto-8.342.07.3 (build 1.8.0_342-b07) OpenJDK 64-Bit Server VM Corretto-8.342.07.3 (build 25.342-b07, mixed mode)

asia.csv log file is here: c-tetrad.txt corresponding json file here: c-tetrad_graph.json.txt

Additional info: This is the verbose of TETRAD-GUI. This could mean the TETRAD-GUI has this bug.
