distrExOptions {distrEx}

Function to change the global variables of the package ‘distrEx’

Description

With distrExOptions you can inspect and change the global variables of the package distrEx.

Usage

distrExOptions(...)
distrExoptions(...)
getdistrExOption(x)

Arguments

...

any options can be defined, using name = value or by passing a list of such tagged values.

x

a character string holding an option name.

Value

distrExOptions() returns a list of the global variables.
distrExOptions(x) returns the global variable x.
getdistrExOption(x) returns the global variable x.
distrExOptions(x=y) sets the value of the global variable x to y.

distrExoptions

For compatibility with spelling in package distr, distrExoptions is just a synonym to distrExOptions.

Global Options

MCIterations:

number of Monte-Carlo iterations used for crude Monte-Carlo integration; defaults to 1e5.

GLIntegrateTruncQuantile:

If integrate fails and there are infinite integration limits, the function GLIntegrate is called inside of distrExIntegrate with the corresponding quantiles GLIntegrateTruncQuantile respectively, 1 - GLIntegrateTruncQuantile as finite integration limits; defaults to 10*.Machine$double.eps.

GLIntegrateOrder:

The order used for the Gauss-Legendre integration inside of distrExIntegrate; defaults to 500.

ElowerTruncQuantile:

The lower limit of integration used inside of E which corresponds to the ElowerTruncQuantile-quantile; defaults to 1e-7.

EupperTruncQuantile:

The upper limit of integration used inside of E which corresponds to the (1-ElowerTruncQuantile)-quantile; defaults to 1e-7.

ErelativeTolerance:

The relative tolerance used inside of E when calling distrExIntegrate; defaults to .Machine$double.eps^0.25.

m1dfLowerTruncQuantile:

The lower limit of integration used inside of m1df which corresponds to the m1dfLowerTruncQuantile-quantile; defaults to 0.

m1dfRelativeTolerance:

The relative tolerance used inside of m1df when calling distrExIntegrate; defaults to .Machine$double.eps^0.25.

m2dfLowerTruncQuantile:

The lower limit of integration used inside of m2df which corresponds to the m2dfLowerTruncQuantile-quantile; defaults to 0.

m2dfRelativeTolerance:

The relative tolerance used inside of m2df when calling distrExIntegrate; defaults to .Machine$double.eps^0.25.

nDiscretize:

number of support values used for the discretization of objects of class "AbscontDistribution"; defaults to 100.

hSmooth:

smoothing parameter to smooth objects of class "DiscreteDistribution". This is done via convolution with the normal distribution Norm(mean = 0, sd = hSmooth); defaults to 0.05.

IQR.fac:

for determining sensible integration ranges, we use both quantile and scale based methods; for the scale based method we use the median of the distribution \pm IQR.fac\times the IQR; defaults to 15.

propagate.names.functionals

should names obtained from parameter coordinates be propagated to return values of specific S4 methods for functionals; defaults to TRUE.
