• What is the cause and solution for SAP error message TRM_REGR_TOOL1010 - Sigma is zero; F ratio computation is not possible ?

  The SAP error message TRM_REGR_TOOL1010 indicates that during a regression analysis, the Sigma (standard deviation) is zero, which means that there is no variability in the data being analyzed. This situation makes it impossible to compute the F-ratio, which is a statistical measure used to compare variances.
  
  Cause:
  
  Lack of Variability: The most common cause of this error is that the dependent variable (the variable you are trying to predict) has no variation. For example, if all the values of the dependent variable are the same, the standard deviation will be zero.
  Insufficient Data: If there are not enough data points or if the data points are not varied enough, this can lead to a situation where the regression analysis cannot be performed.
  Incorrect Data Input: There may be an issue with how the data was input or structured, leading to a lack of variability.
  
  
  Solution:
  
  Check Data Variability: Review the dataset to ensure that the
