These functions are all methods
for class rglmb
or summary.rglmb
objects.

the number of significant digits to use when printing. |

Additional optional arguments |
The summary.rglmb
function summarizes the output from the
rglmb
function. It takes an object of class rglmb
as an input.
The output to a large extent mirrors the output from the summary.glm
function. This is particularly true for the print output from the function
(i.e. the output of the function print.summary.rglmb
).
summary.rglmb
returns a object of class "summary.rglmb"
, a
list with components:
n |
number of draws generated |
coefficients1 |
Matrix with the prior mean and approximate weight for the prior relative to the data |
coefficients |
Matrix with columns for the posterior mode, posterior mean, posterior standard deviation, monte carlo error, and tail probabilities (posterior probability of observing a value for the coefficient as extreme as the prior mean) |
Percentiles |
Matrix with estimated percentiles associated with the posterior density |
