create_testset {prcbench} | R Documentation |
Create a list of test datasets
Description
The create_testset
function creates test datasets either for
benchmarking or curve evaluation.
Usage
create_testset(test_type, set_names = NULL)
Arguments
test_type |
A single string to specify the type of dataset generated by
this function.
- "bench"
Create test datasets for benchmarking
- "curve"
Create test datasets for curve evaluation
|
set_names |
A character vector to specify the names of test
datasets.
For benchmarking (test_type = "bench" )
This function uses a naming convention for randomly generated data for
benchmarking. The format is a prefix ('i' or 'b') followed by the number of
dataset. The prefix 'i' indicates a balanced dataset, whereas 'b'
indicates an imbalanced dataset. The number can be used with a suffix 'k'
or 'm', indicating respectively 1000 or 1 million.
Below are some examples.
- "b100"
A balanced data set with 50 positives and 50
negatives.
- "b10k"
A balanced data set with 5000 positives and 5000
negatives.
- "b1m"
A balanced data set with 500,000 positives and 500,000
negatives.
- "i100"
An imbalanced data set with 25 positives and 75
negatives.
The function returns a list of TestDataB objects.
For curve evaluation (test_type = "curve" )
The following three predefined datasets can be specified for curve
evaluation.
The function returns a list of TestDataC objects.
