                        HIERARCHICAL MULTIPLE REGRESSION


   This program enables you to conduct both simultaneous and hierarchical
   multiple regression analysis using up to 50 independent variables. You
   may enter a raw data file or a summary data file.

   You may input a raw data file that has 200 or fewer variables and then 
   select up to 51 variables for use in conducting the regression analysis. 
   If you choose to enter a summary data file, it may contain data for up
   to 51 variables.

   The procedure permits use of a raw data or summary data input file.
   If you want to learn how to construct such input data files, return to
   the main menu and select the "Learn" option. Information will then be
   provided in regards to the use of missing data codes and case or variable
   deletion options.

                               EXAMINING INPUT DATA


    You have the option here of examining the names of your variables, their
    means, and the standard deviations. This option is presented as another
    way of confirming that you are using the data that you desire.

                                 SINGULAR MATRIX


    The correlation matrix for your independent variables is singular, it has
    no inverse, the determinant equals 0.0, and a final solution cannot be
    obtained. You may remedy this problem by deleting a variable. You will be
    told which is the offending variable.

    This is a fatal error and the program will terminate. Please note the
    information given when you press the next key.

                                TOO MANY VARIABLES


   This program will allow you to use a summary data file that has a maximum 
   of 51 variables. You have entered a file that contains more than 51 vari-
   ables. The remedy is to reduce the number of variables in the input file.
