This is a boilerplate function to create automatically the following:
recipe
model specification
workflow
calibration tibble and plot
Usage
ts_auto_lm(
.data,
.date_col,
.value_col,
.formula,
.rsamp_obj,
.prefix = "ts_lm",
.bootstrap_final = FALSE
)
Arguments
- .data
The data being passed to the function. The time-series object.
- .date_col
The column that holds the datetime.
- .value_col
The column that has the value
- .formula
The formula that is passed to the recipe like
value ~ .
- .rsamp_obj
The rsample splits object
- .prefix
Default is
ts_lm
- .bootstrap_final
Not yet implemented.
Details
This uses parsnip::linear_reg()
and sets the engine
to lm
