Returns a simple linear regression model, a linear regression model with a single
explanatory variable
Usage
ml.lm(form, mlDf)
Arguments
form
an object of class "formula" (or one that can be coerced to that class): a symbolic description of the model to be fitted.
mlDf
an ml.data.frame object
Details
The function eliminates all pairs for which either the first field or the second field
is empty. After the elimination, if the length of the input is less than 2, the function
returns the empty sequence. After the elimination, if the standard deviation of the
independent variable is 0, the function returns a linear model with intercept = the mean
of the dependent variable, coefficients = NaN and r-squared = NaN.
After the elimination, if the standard deviation of the dependent variable is 0,
the function returns a linear model with r-squared = NaN.
