)A dataframe of xreg (exogenous regressors)
A numeric vector of values to fit
a Boolean value for select a seasonal random walk instead
an optional integer value for the seasonal period.
An integer of the number of Markov Chains chains to be run, by default 4 chains are run.
An integer of total iterations per chain including the warm-up, by default the number of iterations are 2000.
A positive integer specifying number of warm-up (aka burn-in) iterations. This also specifies the number of iterations used for step-size adaptation, so warm-up samples should not be used for inference. The number of warmup should not be larger than iter and the default is iter/2.
An optional real value between 0 and 1, the thin of the jumps in a HMC method. By default is 0.9
An integer of the maximum depth of the trees evaluated during each iteration. By default is 10.
An integer with the seed for using when predicting with the model.
