• What is the cause and solution for SAP error message TRM_REGR_TOOL1009 - Standard error is zero; T stat. computation is not possible ?

  The SAP error message TRM_REGR_TOOL1009 indicates that there is an issue with the statistical computation of the T-statistic in the context of regression analysis. The specific message "Standard error is zero; T stat. computation is not possible" suggests that the regression model has encountered a situation where the standard error of the regression coefficients is zero. This typically occurs when there is insufficient variability in the data or when the model is not properly specified.
  Causes:
  
  Insufficient Data Variability: If the dependent variable does not vary (e.g., all values are the same), the standard error cannot be computed.
  Perfect Multicollinearity: If one or more independent variables are perfectly correlated with each other, it can lead to a situation where the model cannot estimate the coefficients properly.
  Too Few Data Points: If there are not enough observations relative to the number of predictors, it can lead to issues in estimating the standard error.
  Incorrect Model Specification:
