cov_mat | R Documentation |
Extract various sigma matrices
cov_mat(obj, which = c("xy", "zy", "zw"), use_population = TRUE)
obj |
A simrel object |
which |
A character string to specify which covariance matrix to extract, possible values are "xy", "zy" and "zw" |
use_population |
A boolean whether to use compute population values or to estimate from sample |
A matrix of covariances with column equals to the number of response and row equals to the number of predictors
set.seed(1983) sobj <- multisimrel() cov_mat(sobj, which = "xy", use_population = TRUE) cov_mat(sobj, which = "xy", use_population = FALSE)
