Description Usage Arguments Value
Computes a simple model-based bootstrap confidence interval for success of joint diagonalization procedure. The model-based bootstrap approach assumes normally distributed error terms; the parameters of the noise distribution are estimated with maximum likelihood.

Ahat |
Estimated connectivity matrix returned by |
X |
A (nxp)-dimensional matrix (or data frame) with n observations of p variables. |
ExpInd |
Indicator of the experiment or the intervention type an observation belongs to. A numeric vector of length n. Has to contain at least three different unique values. |
nrep |
Number of bootstrap samples. |
alpha |
Significance level for confidence interval. |
covariance |
A boolean variable. If |
baseInd |
Index for baseline environment against which the intervention variances are measured. Defaults to 1. |
tolerance |
Precision parameter for |
