  id_col = NULL,
  time_col = "ds",
  target_col = "y",
  level = NULL,
  quantiles = NULL,
  finetune_steps = 0,
  finetune_loss = "default",
  clean_ex_first = TRUE,
  model = "timegpt-1"
)

Value

'TimeGPT''s forecast for the in-sample period.

A tsibble or a data frame with time series data.

freq

Frequency of the data.

id_col

Column that identifies each series.

time_col

Column that identifies each timestep.

target_col

Column that contains the target variable.

level

The confidence levels (0-100) for the prediction intervals.

quantiles

Quantiles to forecast. Should be between 0 and 1.

finetune_steps

Number of steps used to finetune 'TimeGPT' in the new data.

finetune_loss

Loss function to use for finetuning. Options are: "default", "mae", "mse", "rmse", "mape", and "smape".

clean_ex_first

Clean exogenous signal before making the forecasts using 'TimeGPT'.
