| FLAG | FLAG is the main function to fulfill the whole process. |
| FlagOneEdge | Use FLAG to infer one edge. Given n*p data matrix, when we only interest in the conditional dependence between i-th and j-th variables. |
| FlagOnePair | FLAG for one pair of random variables, using random effects model. This is a repeated function for FLAG. |
| FlagOnePairEta0 | FLAG for one pair of random variables fixing eta as zero, using likelihood-ratio test. |
| GetSeRho | Get the standard error of rho. |
| InferWald | Infer by the Wald test. |
