kandi X-RAY | screening Summary

screening is a R library typically used in Artificial Intelligence, Machine Learning, Pytorch applications. screening has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This package implements four popular variable screening algorithms, the sure independence screening1 (SIS), high-dimensional ordinary least squares projection2 (HOLP), rank-robust correlation screening3 (RRCS) and the Forward regression4 (FR) for efficient screening operation over large p small n models. SIS, HOLP and FR are implemented to work with both linear models and generalized linear models while RRCS works only for linear models. We refer the reader to the references and the R-help docs for detailed information.

            For these sort of problems where you need to map names to names, I like to use named vectors (with the function setNames()) the way you would use dictionaries in python. Then you can use it to extract the vector of labels that you want to prepend to each data.frame.

            Calculating p-values from a tbl_merge object?
            Asked 2021-May-06 at 11:58

            I have been using the R function gtsummary, but have now run into a problem with variables existing in subsets of each other. I have two screening tests that can independently be positive of one another which has created an issue with using by = with tbl_summary. This lead me to create two separate tables and combine them with the tbl_merge function.

            However, I would like to calculate p-values for differences between the tests. Is there any way to do this with an object in the table_merge format or to extract information from it and calculate the statistics I need?

            Per request, I post a code example from the mtcars database.

            I think the code example solves your problem. You'll need to supplement the code with a proper comparison of the two columns that takes into account that the two groups are not mutually exclusive.

            Install screening

            To install the package in a painless way, you will need to first install devtools package and then execute the following lines in your favorate R IDE. The package is now ready for use. Simply call the helper by typing. will provide further information on the usage of the function. If there is any issue installing the devtools package, you may instead downlowd the R files from directory /R directly. The file screening.r contains all working functions required for using the algorithm.
            A simple working example. Assume we observe 200 samples with 500 dimension, stored in x and y. Following code illustrates screening using a linear model. output$screen contains the indexes of the screened variables, which, in this case, is a 50-dimensional vector. If you opt to use extended BIC for determining the screening set, then simply replace the second line in the above code with. The package contains other two testing functions linearModelTest and logisticTest. The two functions provide integrated tests on the four screening methods. The full functionality includes simulating synthetic datasets and apply screening methods and report the result. Their codes also serve as good examples of using screening. For more detailed information, please refer to their R-help docs.
