Fitting linear models and generalized linear models with large data sets in R

We present an estimating algorithm to fit linear and generalized linear modelsnot involving the QR decomposition. Some new R functions are presented and discussed.For large data sets, comparisons with respect to the well-known lm() and glm(), as well asto biglm() and bigglm() from the package biglm, show that the proposed functions speedup computation while preserving numerical stability and accuracy
