An object of class uncert
Number of digits to display in budget and (if present) distribution parameter lists.
If TRUE, strings in uncertainty budget are right-justified.
This differs from the default in
Other parameters passed to
summary.uncert simply calls
An object of class "uncert" contains:
The matched call
The calculated value (for function, expression or formula methods) or NA
The combined standard uncertainty
The uncertainty evaluation method used.
A data frame consisting of:
x (if supplied; otherwise a vector of NA's).
The standard uncertainties in input quantities (originally provided as
The degrees of freedom asscociated with
Sensitivity coefficients either provided as
c or (for the formula, function
and expression methods) as calculated.
The product of
c. These are the contributions to the
combined uncertainty for uncorrelated quantities.
Any relevant parameters other than those in $budget$x (typically addditional constants passed to function or expression methods)
If available, a named list of the distributions associated with
The list contains either root nams of distribution functions (e.g
If available, a list of lists of parameters describing the
distributions associated with
The covariance matrix used
The correlation matrix used
A data frame of covariances between x and y. Row names correspond to the correlation method used. For all uncertainty evaluation methods but MC, the only correlation calculation is "theoretical"; for MC row names include all methods supported by stats::cor at the time the object was created.
A data frame of correlations between x and y, of the same form as
For the formula and expression methods, the result of a call to
an expression which evaluates to the value with attributes corresponding to the derivatives
(that is, an expression which can be evaluated to give the value and sensitivity coefficients)
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
suppressed if all NA (typically df when not specified).
summary is currently an alias for the print method.
