How To Fix RSAN_RT306 - Standardized regression coefficients

SAP Error Message - Details

• Message type: E = Error

• Message class: RSAN_RT - Messages for Runtime Analysis

• Message number: 306

• Message text: Standardized regression coefficients

What causes this issue?

Standardization allows the regression coefficients to be compared
because standardization eliminates the influence that the different
value ranges for the variables have on the regression coefficients. The
standardized regression coefficient is calculated from the regression
coefficient aj as follows:
aj(standardized) = aj * Standard Deviation(xj) / Standard Deviation(x0)

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message RSAN_RT306 - Standardized regression coefficients ?

  The SAP error message RSAN_RT306, which pertains to "Standardized regression coefficients," typically arises in the context of SAP BW (Business Warehouse) or SAP Analytics when dealing with regression analysis in the context of data mining or predictive analytics.
  Cause:
  The error RSAN_RT306 can occur due to several reasons, including:
  
  
  Data Issues: The dataset being used for regression analysis may have missing values, outliers, or insufficient data points, which can lead to problems in calculating standardized regression coefficients.
  
  
  Model Configuration: There may be issues with the configuration of the regression model itself, such as incorrect settings or parameters that do not align with the data being analyzed.
  
  
  Technical Limitations: The system may have limitations in terms of memory or processing power, especially if the dataset is large or complex.
  
  
  Version Compatibility: There may be compatibility issues with the version of SAP BW or the specific components being used for regression analysis.
  
  
  Solution:
  To resolve the RSAN_RT306 error, consider the following steps:
  
  
  Data Validation: Check the dataset for missing values, outliers, or any inconsistencies. Clean the data as necessary to ensure it is suitable for regression analysis.
  
  
  Model Review: Review the configuration of the regression model. Ensure that all parameters are set correctly and that the model is appropriate for the data being analyzed.
  
  
  System Resources: Monitor system resources to ensure that there is enough memory and processing power available. If necessary, optimize the system or consider running the analysis on a smaller subset of data.
  
  
  Update Software: Ensure that you are using the latest version of SAP BW and any relevant components. Check for patches or updates that may address known issues.
  
  
  Consult Documentation: Refer to SAP documentation or support resources for specific guidance related to the RSAN_RT306 error. This may include troubleshooting steps or best practices for regression analysis.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with a technical expert who specializes in SAP BW and predictive analytics.
  
  
  Related Information:
  
  SAP BW Documentation: Review the official SAP BW documentation for insights into regression analysis and error handling.
  SAP Community: Engage with the SAP Community forums where other users may have encountered similar issues and can provide insights or solutions.
  Data Mining and Predictive Analytics: Familiarize yourself with the principles of data mining and predictive analytics, as understanding these concepts can help in troubleshooting and optimizing your models.
  
  By following these steps, you should be able to address the RSAN_RT306 error and successfully compute standardized regression coefficients in your SAP environment.
