Extract the standard errors of estimated coefficients
Description
The standard errors are a key element while presenting the results
of a model. They are the second column of the table of coefficient
and are used to compute the t/z-value. stder
enables to retrieve
easily the vector of standard errors, either from a fitted model or
from a matrix of covariance
Usage
stder(x, vcov, subset = NA, fixed = FALSE, grep = NULL, invert = FALSE, ...)
## Default S3 method:
stder(
x,
vcov = NULL,
subset = NA,
fixed = FALSE,
grep = NULL,
invert = FALSE,
...
)
Arguments
x |
a fitted model or a matrix of covariance |
vcov |
a function that computes a covariance matrix, or a character |
subset , grep , fixed , invert |
invert see 'micsr::select_coef |

Value
a numeric vector
