Use of displays with packaged statistical programs

Abstract

During the past few years there has been a great increase in the use of packaged statistical programs. These programs are prepared in a general form. For example, a regression program will allow the user to specify: the number of variables being introduced as a data set the number of cases the choice from this data set of the dependent variable the choice of some subset of the input variables to be the independent variables the type of input (cards vs. tapes, etc.) the transformation of any variable in the data set the construction of new variables for some stated function of the input variables the stepwise computation of regression function the priority with which variables may be considered for introduction into the regression equation the plotting of residuals vs. various input variables.
