jVaRLim: Value at Risk Function(under price limit condition)

Description

Compute VaR under price limit condition.

See the report: Value at Risk.

Usage

jVaRLim(Ret, L, U, alpha, type, h)

Arguments

Ret

A return series that computed from price series.

L

Lower limit.

U

Upper limit.

alpha

Given probability of the event that loss exceeds VaR.

type

Computing method.

'model': Garch(1,1) method.

'histl': Historical method with return series adjusted by Garch(1,1) method.

'simul': Simulation method.

h

Time point of VaR computing (...,-1,0,1,...)

. -1 : previous day . 0 : present . 1 : next day

Value

Value at Risk at the time point.
