     This dialog is used to specify a generalized linear model to be
     fit by the  'glm' function.

_D_e_t_a_i_l_s:

     Enter a name for the generalized linear model to be fit if you
     want to retain more than one model.  The model  name must be a
     valid R object name (consisting only of upper and lower-case
     letters, numerals, and periods, and not starting with a numeral).

     The left model-formula box specifies the response variable to be
     used in the model; it may be a variable name or an expression
     evaluating to the response variable, such as 'working ==
     "Fulltime"'.

     The right model-formula box specifies the right-hand (i.e.,
     predictor) side of the model. See 'glm' for details.

     You can type directly in the model formula boxes. Alternatively,
     double-clicking the left mouse button on a variable in the
     variable-list transfers it to the left-hand side of the model (if
     it is empty) or to the right-hand side.  Factors are indicated in
     the variable list; all other variables are numeric. You can also
     enter operators and parentheses using the buttons above the
     formula.

     Double-click the left mouse button to select a family in the
     "Family" box and the corresponding permissible link functions
     appear in the "Link function" box to the right. Initially, the
     canonical link for the family is selected. See 'family' for
     details.

     Specifying a subset expression allows you to fit the model to a
     subset of observations in the active data set. For example,
     assuming that 'gender' is a variable in the active data set,
     entering 'gender == "Male"' would restrict the model to males.

     If the active model is a generalized linear model, and the active
     data set has not changed,  then the initial values of the
     left-hand-side, right-hand-side, family, link, and subset fields
     are retained from the active model.
