Linear optm
NettetLinear regression is a prediction method that is more than 200 years old. Simple linear regression is a great first machine learning algorithm to implement as it requires you to estimate properties from your training dataset, but is simple enough for beginners to understand. In this tutorial, you will discover how to implement the simple linear … NettetTo construct an Optimizer you have to give it an iterable containing the parameters (all should be Variable s) to optimize. Then, you can specify optimizer-specific options such …

Nettetmethod. a string containing the method to use, either "Evanno", "linear", or "SiZer". Default is "Evanno". ignore. a numeric vector of whole numbers indicating migration edges to ignore. Useful when running Treemix on a prebuilt tree (ignore = 0). Default is NULL.

To run OptM, you will need a folder of output files produced by Treemix v1.13 or OrientAGraph. The function optM will automatically search the folder for the stem.llik, stem.modelcov.gz, and stem.cov.gz files; where "stem" is that provided to the -o parameter of treemix. It is recommended, but not required, to use … Se mer This package uses results from the population software 'Treemix' by Pickrell and Pritchard (2012) DOI:10.1371/journal.pgen.1002967 to estimate the optimal … Se mer
