Quick Start
-----------
Procedural approach
~~~~~~~~~~~~~~~~~~~
.. code:: python
from SALib.sample import saltelli
from SALib.analyze import sobol
from SALib.test_functions import Ishigami
import numpy as np
problem = {
'num_vars': 3,
'names': ['x1', 'x2', 'x3'],
'bounds': [[-np.pi, np.pi]]*3
}
# Generate samples
param_values = saltelli.sample(problem, 1024)
# Run model (example)
Y = Ishigami.evaluate(param_values)
# Perform analysis
Si = sobol.analyze(problem, Y, print_to_console=True)
# Returns a dictionary with keys 'S1', 'S1_conf', 'ST', and 'ST_conf'
# (first and total-order indices with bootstrap confidence intervals)
It's also possible to specify the parameter bounds in a file with 3
columns:
::
# name lower_bound upper_bound
P1 0.0 1.0
P2 0.0 5.0
...etc.
Then the ``problem`` dictionary above can be created from the
``read_param_file`` function:
.. code:: python
from SALib.util import read_param_file
problem = read_param_file('/path/to/file.txt')
# ... same as above
Lots of other options are included for parameter files, as well as a
command-line interface. See the `advanced
section in the documentation <https://salib.readthedocs.io/en/latest/advanced.html>`__.
Method chaining approach
~~~~~~~~~~~~~~~~~~~~~~~~
Chaining calls is supported from SALib v1.4
.. code:: python
from SALib import ProblemSpec
from SALib.test_functions import Ishigami
import numpy as np
# By convention, we assign to "sp" (for "SALib Problem")
sp = ProblemSpec({
'names': ['x1', 'x2', 'x3'], # Name of each parameter
'bounds': [[-np.pi, np.pi]]*3, # bounds of each parameter
'outputs': ['Y'] # name of outputs in expected order
})
(sp.sample_saltelli(1024, calc_second_order=True)
.evaluate(Ishigami.evaluate)
.analyze_sobol(print_to_console=True))
print(sp)
# Samples, model results and analyses can be extracted:
print(sp.samples)
print(sp.results)
print(sp.analysis)
# Basic plotting functionality is also provided
sp.plot()
The above is equivalent to the procedural approach shown previously.
Also check out the `FAQ <https://github.com/SALib/SALib/tree/main/FAQ.MD>`__ and
`examples <https://github.com/SALib/SALib/tree/main/examples>`__ for a
full description of options for each method.
