set.lambda: Set mean signal magnitude

In BBEST: Bayesian Estimation of Incoherent Neutron Scattering Backgrounds

Description

set.lambda sets the mean height of the peaks over region x.

Usage

set.lambda(data, lambda=NA, lambda_1=NA, lambda_2=NA, 
           lambda_0=NA, x_1=NA, x_2=NA)

Arguments

data	an object of type data. See set.data for details.
lambda	numeric vector. If not NA, specifies (approximate) the mean magnitude of the signal. This estimate does not need to be accurate. lambda can be estimated as a smooth function that crosses centres of the signal peaks.
lambda_1, lambda_2, lambda_0, x_1, x_2	numerics. If lambda is NA help to estimate lambda. See details.

Details

lambda is calculated as a linear piecewise function which is equal to lambda_0 outside the [x_1,x_2] region. Inside this region, lambda is approximated by a line connecting points (x_1;lambda_1) and (x_2;lambda_2).

Value

An object of type data. Element

lambda

numeric vector containing an approximate mean magnitude of the signal.
