Description

Provide tools for structural reliability analysis (failure probability, quantile).

Details

Package:	mistral
Type:	Package
Version:	2.2.1 Date:	2016-12-21
License:	CeCILL

This package provides tools for structural reliability analysis:

• Calculate failure probability with FORM method and importance sampling.

• Calculate failure probability with crude Monte Carlo method

• Calculate failure probability with Subset Simulation algorithm

• Calculate failure probability with Monotonic Reliability Methods (MRM)

• Calculate failure probability with metamodel based algorithms : AKMCS, SMART and MetaIS

• Calculate failure probability with a metamodel based Subset Simulation : S2MART

• Wilks formula: Compute a quantile (or tolerance interval) with a given confidence level from a i.i.d. sample,

• Wilks formula: Compute the minimal sample size to estimate a quantile with a given confidence level,

• Calculate a quantile under monotonicity constraints

########## FORM ########### 
# u.dep is a starting point for the research of the Most Probable Failing Point
# N.calls is a total number of calls

                    u.dep = c(0,0))

# use IS=TRUE to use an Importance Sampling scheme with a Gaussian standard
# proposal distribution centred at the MPFP
