simulate,mixedRegression-method {BaPreStoPro} | R Documentation |
Simulation of regression model y_{ij} = f(φ_j, t_{ij}) + ε_{ij}, φ_j\sim N(μ, Ω), ε_{ij}\sim N(0,γ^2\widetilde{s}(t_{ij})).
## S4 method for signature 'mixedRegression' simulate(object, nsim = 1, seed = NULL, t, plot.series = TRUE)
object |
class object of parameters: "mixedRegression" |
nsim |
number of data sets to simulate. Default is 1. |
seed |
optional: seed number for random number generator |
t |
vector of time points |
plot.series |
logical(1), if TRUE, simulated series are depicted grafically |
