SingVarRiskSummaries {bkmr} | R Documentation |
Compute summaries of the risks associated with a change in a single variable in Z
from a single level (quantile) to a second level (quantile), for the other variables in Z
fixed to a specific level (quantile)

An object containing the results returned by a the |

a vector of outcome data of length |

which.z |
vector indicating which variables (columns of |
qs.diff |
vector indicating the two quantiles |
q.fixed |
vector of quantiles at which to fix the remaining predictors in |
method |
method for obtaining posterior summaries at a vector of new points. Options are "approx" and "exact"; defaults to "approx", which is faster particularly for large datasets; see details |
sel |
logical expression indicating samples to keep; defaults to keeping the second half of all samples |
z.names |
optional vector of names for the columns of |

If method == "approx"
then calls the function ComputePostmeanHnew.approx
. In this case, the argument sel
defaults to the second half of the MCMC iterations.
If method == "exact"
then calls the function ComputePostmeanHnew.exact
. In this case, the argument sel
defaults to keeping every 10 iterations after dropping the first 50% of samples, or if this results in fewer than 100 iterations, than 100 iterations are kept
