Conditional Expectation with Inequalities

Description

Conditional Expectation with Inequalities

Usage

simcond(dbin, dbout, model = model.input(), seed = 232431, nbsimu = 1, nbtuba = 100, nboot = 10, niter = 100, flag.check = FALSE, flag.ce = FALSE, flag.cstd = FALSE, verbose = FALSE, radix = "SimCond", modify.target = db.locmod())

Arguments

`dbin`	The `db-class` structure containing the information. This information must be constituted by inquality constraints and/or hard data. See Details
`dbout`	The `db-class` strcture where the calculations must be performed.
`model`	The `model-class` containing the Model information. For more information check `check.model`.
`seed`	Seed used for the random number generator. When 0, the seed is not initialized.
`nbsimu`	Number of simulations
`nbtuba`	Number of bands used for the internal Turning Bands simulation algorithm
`nboot`	Number of iterations performed for bootstrap
`niter`	Maximum number of iterations for calculating the conditional expectation
`flag.check`	When TRUE, the Gaussian value of the conditional simulation is compared to the value of the closest data.
`flag.ce`	When TRUE, the Conditional Expectation is derived from the simulations
`flag.cstd`	When TRUE, the Conditional Standard Deviation is derived from the simulations
`verbose`	Verbose flag
`radix`	Radix of the name given to the variables storing the results in the target Db.
`modify.target`	Decides whether or not the newly created variables will have their locator defined or not. For more information, see `db.locmod`. In the case of 'flag.ce' and / or 'flag.cstd', locators are defined only for the output fields containing Conditional Expectation.

Details

At a constrining sample:

When the lower and the upper bound are provided: the upper bound must be larger than lower bound,
When the lower bound (or the upper bound) is provided alone: the undefined bound is considered as infinite,
When a hard data is provided: this data prevails whether or not the bounds are provided. A warning message is issued is the hard data does not lie between the bounds

When no bound is provided, a message is provided to encourage using simtub() instead of simcond().

Value

The target Db to which several variables have been added:

if 'flag.ce' is specified: the Conditional Expectation variable
if 'flag.cstd' is specified: the Conditional Standard Deviation variable
otherwise, one new variable per simulation
