RegularizationOverview and RationaleIn order to consolidate your theoretical knowledge into technique and skills with practicaland applicational value, you will use the glmnet() package in R to implement LASSOfunction to build linear and logistic models through LASSO over values of regularizationparameter lambda.Course OutcomesThis assignment is directly linked to the following key learning outcomes from the coursesyllabus:• Conduct regularization method for models to describe relationships amongvariables and make useful predictionsAssignment SummaryUse one of the real world example data sets from R (not previously used in the R practiceassignment) or a dataset you have found, to build regularization models by using Lasso(least absolute shrinkage and selection operator) and extend Lasso model fitting to big datathat cannot be loaded into memory. You will fit solution paths for linear or logisticregression models penalized by Lasso over a grid of values for the regularizationparameter lambda.Use the resources in this module to guide your R code development.ReportYour assignment/project should have a good cover/title page, introduction of what thegoals of the project and the methods you use. It also should follow APA format with at least1000 words (excluding title page and references page) and references page. In the body ofyour project you should incorporate the R codes and R outputs with interpretation of yourresults. Be sure to show all the elements in the official hypothesis, including the null andalternative hypothesis, the critical values, calculation of the test statistics and p-values.Finally, you need to make sense of your results to make good points with properconclusions, to show your understanding of the course material and its application to thedataset.Graphs, figures, charts, tables are very useful to increase visual effects to impress yourreaders. You also should do your best to give insight and understanding to the project witha good conclusion. Please use subtitles to make your assignment more reader friendly aswell.Assignment RubricCategory Meets Standards Approaching Standards Below StandardsIntroductionIntroduction provides abrief and intelligibleoverview of the goals andmethods of theassignmentIntroduction provides anoverview of the goals andmethods of theassignment, but isambiguous or not conc代写LASSO、代做R程序语言、代写linear、代做R设计iseDoes not introduceproject goals, projectquestions or methods.AnalysisProvides all R code andthe outputs.
