Cyclops (Cyclic coordinate descent for logistic, Poisson and survival analysis) is an R package for performing large scale regularized regressions.
In the SelfControlledCaseSeries package we fit conditional Poisson regressions, with >100,000 strata and 20 covariates, of which 18 (representing season and calendar time) can be regularized. We need a likelihood...
Hi, I hope this is not the wrong place to ask questions. I am new to R and gpu computing, and I am trying to run this [script](https://github.com/suchard-group/gpu_survival_analysis_supplement) with gpu_cox....
`BH` is ungodly large and very slow to unpack in some data-source environments.
Under specific circumstances, the following warning is thrown: ``` as(, "dgeMatrix") is deprecated since Matrix 1.5-0; do as(as(as(., "dMatrix"), "generalMatrix"), "unpackedMatrix") instead ``` I suspect this originates [here](https://github.com/OHDSI/Cyclops/blob/4066f12912ccaebb16ca081d36eff77e929e26c1/R/DataManagement.R#L284). The following...
Hi, I ran a study package using the CohortMethod and Cyclops, but I got this error like below. I think that there is a problem with the fitting steps of...
Sometimes the confint() function returns upper and lower CI bounds that are identical but the fit$return_flag is “SUCCESS”. Other times, on the same data, it doesn’t – in the latter...
There's a fix for the adaptive grid likelihood profiling [here](https://github.com/OHDSI/Cyclops/commit/7290f73b967e372b9d4e9f6e2bea89fda5ac6802) in its own branch. Could this at some point be merged into main?
Hi @schuemie and @pbr6cornell , If you can generate a dataset with 100,000 or more covariates and many, many rows, I just implemented (in a15bb6615d023d4c8bb59abc3621a67069587dfd) a mode search strategy that...
Hi, @msuchard, Me and @lhjohn are working on transfer learning at ErasmusMC. One of the methods we are interested in evaluation is for linear models and is called the prior...
Just trying to understand: we're fitting a not-so-large logistic regression (for a propensity score) using the exact same data on two platforms (Windows and Linux). The fitted model coefficients are...
