Identify the nonzero partial correlations in one-sample population,
based on controlling the rate of the false discovery proportion (FDP) exceeding c0
at \alpha
, considering time dependence.
Input a popEst
class object returned by population.est
.
population.test(
popEst,
alpha = 0.05,
c0 = 0.1,
targetSet = NULL,
MBT = 5000,
simplify = !is.null(targetSet)
)
popEst |
A |
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. |
If simplify
is FALSE
, a p*p
matrix with values 0 or 1 is returned, and 1 means 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.

## Quick example for the one-sample population inference
data(popsimA)
# estimating partial correlation coefficients by scaled lasso
pc = population.est(popsimA)
# conducting hypothesis test
Res = population.test(pc)
# conducting hypothesis test in variables of interest
set = cbind(rep(7:9, each = 10), 1:10)
Res_like = population.test(pc, targetSet = set)
