Construct confidence intervals and assess p-values in high-dimensional linear and generalized linear models.

x |
The design matrix, of dimensions nxp, without an intercept. Each row is an observation vector. |
y |
The response vector of dimension nx1. Quantitative for family='gaussian', binary (0-1) for family='binomial'. For family='cox', y should be an object of class |
family |
Response type (see above). |
penalty |
The penalty to be applied in the regularized likelihood subproblems. 'lasso' (the default), 'MCP', or 'SCAD' are provided. See package SIS for detail. |
tune |
Method for tuning the regularization parameter of the penalized likelihood subproblems and of the final model selected by (I)SIS. Options include tune='bic', tune='ebic', tune='aic', and tune='cv'. |
alpha1 |
The significance level of correlation screening in the ψ-learning algorithm, see R package equSA for detail. In general, a high significance level of correlation screening will lead to a slightly large separator set, which reduces the risk of missing important variables in the conditioning set. In general, including a few false variables in the conditioning set will not hurt much the accuracy of the ψ-partial correlation coefficient, the default value is 0.1. |
alpha2 |
The significance level of ψ-partial correlation coefficient screening for estimating the adjacency matrix, see equSA, the default value is 0.05. |
level |
the confidence level required, the default value is 0.95 |
CI |
Estimated confidence intervals for all coefficients. |
coef |
px1 estimated regression coefficients for all variables. |
pvalue |
px1 estimated p-values for all variables. |
