ts_sample | R Documentation |
Separates the ts_data
into training and test.
It separates the test size from the last observations minus an offset.
The offset is important to allow replication under different recent origins.
The data for train uses the number of rows of a ts_data
minus the test size and offset.
ts_sample(ts, test_size = 1, offset = 0)
ts |
time series. |
test_size |
integer: size of test data (default = 1). |
offset |
integer: starting point (default = 0). |
