## Identify nonzero individual-level partial correlations

### Description

Identify nonzero individual-level partial correlations in time series data
by controlling the rate of the false discovery proportion (FDP) exceeding `c0`

at `\alpha`

, considering time dependence.
Input an `indEst`

class object returned by `individual.est`

or `population.est`

.

### Usage

```
individual.test(
indEst,
alpha = 0.05,
c0 = 0.1,
targetSet = NULL,
MBT = 3000,
simplify = !is.null(targetSet)
)
```

### Arguments

`indEst` |
An |

`alpha` |
significance level, default value is |

`c0` |
threshold of the exceedance rate of FDP,
default value is |

`targetSet` |
a two-column matrix. Each row contains two index corresponding to a pair of variables of interest.
If |

`MBT` |
times of multiplier bootstrap, default value is |

`simplify` |
a logical indicating whether results should be simplified if possible. |

### Value

If `simplify`

is `FALSE`

, a `p*p`

matrix with values 0 or 1 is returned.
If the j-th row and k-th column of the matrix is 1,
then the partial correlation coefficient between
the j-th variable and the k-th variable is identified to be nonzero.

And if `simplify`

is `TRUE`

, a two-column matrix is returned,
indicating the row index and the column index of recovered nonzero partial correlations.
We only retain the results which the row index is less than the column index.
Those with larger test statistics are sorted first.

# estimating partial correlation coefficients by scaled lasso
pc = individual.est(indsim)
# conducting hypothesis test
Res = individual.test(pc)
