createIhtPrior.RdcreateIhtPrior creates an IHT Cyclops prior object for use with fitCyclopsModel.
createIhtPrior( K, penalty = "bic", exclude = c(), forceIntercept = FALSE, fitBestSubset = FALSE, initialRidgeVariance = 0.1, tolerance = 1e-08, maxIterations = 10000, threshold = 1e-06, delta = 0 )
| K | Maximum # of non-zero covariates |
|---|---|
| penalty | Specifies the IHT penalty; possible values are `BIC` or `AIC` or a numeric value |
| exclude | A vector of numbers or covariateId names to exclude from prior |
| forceIntercept | Logical: Force intercept coefficient into regularization |
| fitBestSubset | Logical: Fit final subset with no regularization |
| initialRidgeVariance | Numeric: variance used for algorithm initiation |
| tolerance | Numeric: maximum abs change in coefficient estimates from successive iterations to achieve convergence |
| maxIterations | Numeric: maximum iterations to achieve convergence |
| threshold | Numeric: absolute threshold at which to force coefficient to 0 |
| delta | Numeric: change from 2 in ridge norm dimension |
An IHT Cyclops prior object of class inheriting from
"cyclopsPrior" for use with fitCyclopsModel.
