ci_fct

solve optimization problem for each coordinate of f, to obtain the uniform
limit.

This is a collection of assorted functions and examples collected
from various projects. Currently we have functionalities for simplifying
overlapping time intervals, Charlson comorbidity score constructors for
Danish data, getting frequency for multiple variables, getting standardized
output from logistic and log-linear regressions, sibling design linear
regression functionalities a method for calculating the confidence intervals
for functions of parameters from a GLM, Bayes equivalent for hypothesis
testing with asymptotic Bayes factor, and several help functions for
generalized random forest analysis using 'grf'.

ci_fct function

<dl><dt>i</dt>
<dd>An index for the point at which to solve for confidence limits.</dd>
<dt>f</dt>
<dd>A function taking the parameter vector as its single argument, and
returning a numeric vector.</dd>
<dt>xtx_red</dt>
<dd>Reduced form of matrix X^TX.</dd>
<dt>beta_hat</dt>
<dd>Vector of parameter estimates.</dd>
<dt>which_parm</dt>
<dd>Vector indicating which parameters to include.</dd>
<dt>level</dt>
<dd>The confidence level required.</dd>
<dt>n_grid</dt>
<dd>Either <code>NULL</code> or an integer vector of length 1 or the number of
<code>TRUE</code>/indices in which_parm. Specifies the number of grid points in each
dimension of a grid with endpoints defined by len. If <code>NULL</code> or <code>0L</code>, will
instead sample k points uniformly on a sphere.</dd>
<dt>k</dt>
<dd>If n_grid is <code>NULL</code> or <code>0L</code>, the number of points to sample
uniformly from a sphere.</dd></dl>
