bm_scale: Mapper for element-wise scaling

In inlabru-org/inlabru: Bayesian Latent Gaussian Modelling using INLA and Extensions

Mapper for element-wise scaling

Description

Create a standalone scaling mapper that can be used as part of a bm_pipe. If mapper is non-null, the bm_scale() constructor returns bm_pipe(list(mapper = mapper, scale = bm_scale()))

Usage

bm_scale(mapper = NULL)

bru_mapper_scale(...)

## S3 method for class 'bm_scale'
ibm_n(mapper, ..., state = NULL, n_state = NULL)

## S3 method for class 'bm_scale'
ibm_n_output(mapper, input, state = NULL, ..., n_state = NULL)

## S3 method for class 'bm_scale'
ibm_values(mapper, ..., state = NULL, n_state = NULL)

## S3 method for class 'bm_scale'
ibm_jacobian(mapper, input, state = NULL, ..., sub_lin = NULL)

## S3 method for class 'bm_scale'
ibm_eval(mapper, input, state = NULL, ..., sub_lin = NULL)

Arguments

mapper	For bm_scale(), an optional bru_mapper to be scaled. For ⁠ibm_*⁠ methods, a bm_scale mapper object.
...	Arguments passed on to other methods
state	A vector of latent state values for the mapping, of length ibm_n(mapper, inla_f = FALSE)
n_state	integer giving the length of the state vector for mappers that have state dependent output size.
input	Data input for the mapper.
sub_lin	Internal, optional pre-computed sub-mapper information

Methods (by generic)

• ibm_jacobian(bm_scale): input NULL values are interpreted as no scaling.
