Rcmdr Linear Model Dialog

This dialog is used to specify a linear model to be fit by the lm function.


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 log(income). The right model-formula box specifies the right-hand (i.e., predictor) side of the model. See lm 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. You can also enter operators and parentheses using the buttons above the formula. 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 linear model and the active data set has not changed, then the initial values of the left-hand-side, right-hand-side, and subset fields are retained from the previous model.
