biglmfreq: Estimates the coefficients of a linear model

Description

Estimates the coefficients of a linear model following the guidelines of biglm

Usage

biglmfreq(formula, data, freq = NULL)
# S3 method for biglmfreq
coef(object, ...)
# S3 method for biglmfreq
predict(object, ...)
# S3 method for biglmfreq
print(x, ...)
# S3 method for biglmfreq
update(object, ...)

Arguments

formula

a model formula

data

data frame that must contain all variables in formula and freq

freq

a string of the variable specifying frequency weights

object

a biglmfreq object

...

See Details

x

a biglmfreq object

Value

A biglmfreq object.

Details

Any variables in the formula are removed from the data set.

It only computes the coefficients of the linear model.

Examples

mt <- biglmfreq(Sepal.Length ~ Sepal.Width, iris)
coef(mt)

chunk1 <- iris[1:30,]

mf1 <- biglmfreq(Sepal.Length ~ Sepal.Width, chunk1)
mf2 <- update(mf1, chunk2)

predict(mf2, iris)
