Here's R-code for in-class examples:

A new version of the IRLS algo for logistic regression. This version adds calculation of covariance matrix for betas.

LogisticRegression(2).R

A new version of glmnet applied to zipcode data. this version does training on all 10 digits and runs against the test set

to calculate error rate on out of sample test-set.

glmnet.R

Some simple examples using spline functions as part of linear least squares fits.

BS.R

Using glmnet to classify iris data

iris.R

Several different basis expansions in conjunction with glmnet to classify sonar data.

Sonar.R

SA heart study with 4 df spline basis expansion.

SAHeartStudy.R

Concrete strength predicting using various combinations of basis expansions

concrete.R

Bone density smoother

ESLr.R

Data Sets:

Concrete Data;

Concrete_Data.csv

Cross-validation plot for 10-digit handwritten zip code character recognition

Generalized Linear Models approximate the data with a curve similar to

Linear Models which approximate the data with a straight line.

In this plot points are approximated with a line (using lm in r)

In this plot points are approximated with a curve (using glm in r)

(the r code used to produce these plots)
