Jira Issue: PUBDEV-3966 Assignee: Tomas Nykodym Reporter: Avkash Chauhan State: Closed Fix Version: 3.10.3.1 Attachments: N/A Development PRs: N/A
Code:
Load packages & start h2o
library(insuranceData) library(h2o) h2o.init()
Load data into h2o
data(AutoClaims) h2odata <- as.h2o(AutoClaims)
Build model in h2o:
predictors <- names(AutoClaims)[!names(AutoClaims) == "PAID"] h2oglm <- h2o.glm(training_frame=h2odata, x=predictors, y="PAID", family="gamma", link="log", lambda_search = TRUE)
Can see that during lambda search 39 models have been created:
regpath <- h2o.getGLMFullRegularizationPath(h2oglm)
Extract coefficients from the final model to create a new GLM
coefs2 = regpath$coefficients[nrow(regpath$coefficients),] model2 <- h2o.makeGLMModel(h2oglm,coefs2)
