biglmfreq: Estimates the coefficients of a linear model

In freqweights: Working with Frequency Tables

Description

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

Usage

biglmfreq(formula, data, freq = NULL)

## S3 method for class 'biglmfreq'
coef(object, ...)

## S3 method for class 'biglmfreq'
predict(object, ...)

## S3 method for class 'biglmfreq'
print(x, ...)

## S3 method for class '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

Details

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

It only computes the coefficients of the linear model.

... should be a data frame when predict. See Examples

... should be a data frame when update. See Examples

Value

A biglmfreq object.

Examples

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

chunk1 <- iris[1:30,]
chunk2 <- iris[-c(1:30),]
mf1 <- biglmfreq(Sepal.Length ~ Sepal.Width, chunk1)
mf2 <- update(mf1, chunk2)

predict(mf2, iris)
