An object of class "uncertMC" inherits from class "uncert". In addition to the contents of the "uncert" object, it contains the results from the MC replication as a list MC. The complete description is:
The matched call
The expression, formula or function supplied to uncertMC
.
The uncertainty evaluation method used (always 'MC').
The number of Monte Carlo replicates used.
A data frame consisting of:
The starting values x
.
The standard uncertainties in input quantities (originally provided as u
)
The degrees of freedom asscociated with u
Sensitivity coefficients estimated from the MC output (see uncertMC
for how this is done).
If available, a named list of the distributions associated with u
.
The list contains either root nams of distribution functions (e.g "norm"
or
function definitions.
If available, a list of lists of parameters describing the
distributions associated with u
.
If supplied, any relevant parameters other than those in $budget$x
(typically addditional constants passed to function or expression methods)
The covariance matrix used
The correlation matrix used
A data frame of covariances between x and y. The Row names correspond
to the correlation method used. For uncertMC
objects only
"pearson"
is currently supported (because "kendall"
and "spearman"
take a very long time to compute)
A data frame of correlations between x and y, of the same form as cov.xy
A list containing:
The value of .Random.seed
when uncertMC
was called.
The B
Monte Carlo replicates of the standard uncertainty
calculated as sd(y)
.
If uncertMC
is called with keep.x=TRUE
, a data frame
whose columns are the Monte Carlo replicates of the variables in x
.
print
and summary
methods invisibly return the original object.
The print method provides a formatted printout of the object. By default,
simplify=TRUE
; this displays a shortened listing. Columns in $data
are
suppressed if all NA.
summary is currently an alias for the print method.
