designed to automate the documentation and validation of your models. + +Designed to be model agnostic, the ValidMind Library provides all the standard functionality without requiring you to rewrite any functions as long as your model is built in Python. + +With a rich array of documentation tools and test suites, from documenting descriptions of your datasets to testing your models for weak spots and overfit areas, the ValidMind Library helps you automate model documentation by feeding the ValidMind Platform with documentation artifacts and test results. + +To install the ValidMind Library: + +```bash +pip install validmind +``` + +To initialize the ValidMind Library, paste the code snippet with the model identifier credentials directly into your development source code, replacing this example with your own: + +```python +import validmind as vm + +vm.init( + api_host = "https://api.dev.vm.validmind.ai/api/v1/tracking/tracking", + api_key = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", + api_secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", + project = "" +) +``` + +After you have pasted the code snippet into your development source code and executed the code, the Python Library API will register with ValidMind.

The selection is dependent on the minimalization of BIC (Bayesian Information Criterion) and AIC (Akaike Information Criterion); these are established statistical tools used for model selection. Furthermore, prior to the commencement of the model fitting process, the algorithm conducts a stationarity test (Augmented Dickey-Fuller test) on each series. + +### Test Mechanism + +Starting off, the `AutoMA` algorithm checks whether the `max_ma_order` parameter has been provided. It consequently loops through all variables in the dataset, carrying out the Dickey-Fuller test for stationarity. For each stationary variable, it fits an ARIMA model for orders running from 0 to `max_ma_order`. The result is a list showcasing the BIC and AIC values of the ARIMA models based on different orders. The MA order, which yields the smallest BIC, is chosen as the 'best MA order' for every single variable. The final results include a table summarizing the auto MA analysis and another table listing the best MA order for each variable. + +### Signs of High Risk + +- When a series is non-stationary (p-value>0.05 in the Dickey-Fuller test), the produced result could be inaccurate. +- Any error that arises in the process of fitting the ARIMA models, especially with a higher MA order, can potentially indicate risks and might need further investigation. + +### Strengths + +- The metric facilitates automation in the process of selecting the MA order for time series forecasting. This significantly saves time and reduces efforts conventionally necessary for manual hyperparameter tuning. +- The use of both BIC and AIC enhances the likelihood of selecting the most suitable model. +- The metric ascertains the stationarity of the series prior to model fitting, thus ensuring that the underlying assumptions of the MA model are fulfilled. + +### Limitations + +- If the time series fails to be stationary, the metric may yield inaccurate results. Consequently, it necessitates pre-processing steps to stabilize the series before fitting the ARIMA model. +- The metric adopts a rudimentary model selection process based on BIC and doesn't consider other potential model selection strategies. Depending on the specific dataset, other strategies could be more appropriate. +- The 'max_ma_order' parameter must be manually input which doesn't always guarantee optimal performance, especially when configured too low. +- The computation time increases with the rise in `max_ma_order`, hence, the metric may become computationally costly for larger values. diff --git a/docs/validmind/tests/data_validation/AutoStationarity.qmd b/docs/validmind/tests/data_validation/AutoStationarity.qmd new file mode 100644 index 000000000..c76731266 --- /dev/null +++ b/docs/validmind/tests/data_validation/AutoStationarity.qmd @@ -0,0 +1,52 @@ +--- +title: "[validmind](/validmind/validmind.qmd).AutoStationarity" +sidebar: validmind-reference +toc-depth: 4 +toc-expand: 4 +# module.qmd.jinja2 +--- + + + +## AutoStationarity + + + +::: {.signature} + +@tags('time_series_data', 'statsmodels', 'forecasting', 'statistical_test') + +@tasks('regression') + +defAutoStationarity(dataset:validmind.vm_models.VMDataset,max_order:int=5,threshold:float=0.05): + +::: + + + +Automates Augmented Dickey-Fuller test to assess stationarity across multiple time series in a DataFrame. + +### Purpose + +The AutoStationarity metric is intended to automatically detect and evaluate the stationary nature of each time series in a DataFrame.

The PSI, along with the proportions of data in each bin for both datasets, are displayed in a summary table, a grouped bar chart, and a scatter plot. + +### Signs of High Risk + +- A high PSI value is a clear indicator of high risk.
