Create a trend specification for model parameters
Description
Create a trend specification for model parameters
Usage
make_trend(
par_names,
cov_names,
kernels,
bases = NULL,
shared = NULL,
trend_pnames = NULL,
premap = TRUE,
pretransform = FALSE
)
Arguments
par_names |
Character vector specifying which parameters to apply trend to |
cov_names |
Character vector specifying which covariates to use for each trend |
kernels |
Character vector specifying which kernel function to use for each trend |
bases |
Optional character vector specifying which base function to use for each trend |
shared |
Named list with entries the parameter names to be shared and the names the new names of the shared parameter. |
trend_pnames |
Optional character vector specifying custom parameter names |
premap |
Logical indicating if trend should be applied before or after parameter mapping |
pretransform |
If !premap, logical indicating if trend should be applied before or after parameter transformation |
Value
A list containing the trend specifications for each parameter
Examples
# Put trend on B and v parameters
trend <- make_trend(
par_names = c("B", "v"),
cov_names = "strial",
kernels = c("exp_incr", "poly3"),
premap = TRUE,
shared = list(shrd = list("B.B0", "v.d1"))
)
get_trend_pnames(trend)
