      hi, The log value -3.1 means that the price is significantly less than 1. This is because, on a logarithmic scale, negative values correspond to numbers between 0 and 1.

    Just a few questions. While fitting a decision tree, isn't a node split into two nodes only? Here, specifically for medium income group, with respect to age, the node has been split into four nodes, instead of two. Also, the two terminal nodes at the extreme left provide the same value of the dependent variable, which is "Bad" credit risk, following the majority class rule. But weren't the two nodes supposed to provide two different values of the dependent variable? Otherwise these terminal nodes would not have been created since they are not providing any different prediction from the node from which they got created (because the goodness of split value is low for the mother node here). Same goes for the terminal nodes at extreme right. Is all this due to the CHAID algorithm being used here?

    • @theoutlier7395
      @theoutlier7395 หลายเดือนก่อน

      CART model supports binary splits. however chaid supports multiple splits

    Sir, can we use this factor as a variable for regression. Also, do we need to consider them as negative values or absolute values?

    • @theoutlier7395
      @theoutlier7395 2 หลายเดือนก่อน

      you can use the factor scores as variables

    • @theoutlier7395
      @theoutlier7395 2 หลายเดือนก่อน

      Also, When interpreting factor scores from factor analysis, it is important to use the scores as they are, including both negative and positive values. These scores indicate the relative positioning of observations along the factor dimensions. Converting them to absolute values would distort the interpretation and relationships identified by the factor analysis. Negative values are meaningful and represent observations that are below the mean of the factor, while positive values are above the mean.
