Specify median for defSurv and genSurv and/or add Weibull distribution

3

survival data is generated in simstudy with an underlying Weibull distribution, which is specified with a shape and scale parameter. A user has suggested being allowed to specify the median...

Unit testing - getting simstudy fully "covered"

@assignUser Having taken my first crack at developing some unit tests for the additions to `genOrdCat`, I've gained an appreciation for what you have set up, and now I have...

Generate multiple predictors and coefficients and outputs with a single function call

3

I would like to implement some version of a function a created in a [blog post](https://www.rdatagen.net/post/any-one-interested-in-a-function-to-quickly-generate-data-with-many-predictors/) a while back. This is how I started the post: **I was contacted about...

Generate data from a specified AUC

3

A user wrote in with this question: **I wonder whether you have an option in this package to simulate data from a given AUC (area under the roc curve)?** There...

Create a rejection-sampling function to sample from non-standard distributions

Maybe nice to have an internal function that provides the ability to generate data from a density function specified as a function.

Sequential dependent simulation

1

I just added some code in the non-prop-odds-assumption [branch](https://github.com/kgoldfeld/simstudy/blob/non-prop-odds-assumption/R/sequential_randomization_poc.R) that shows it is possible to generate data that is sequentially dependent over time. The user would specify a data definition...

In the [unit testing ](https://github.com/kgoldfeld/simstudy/blob/a5d9ec19d8c7210d3f925f49569a8bba08a6b5bd/tests/testthat/test-generate_data.R#L800)the following test (properly) throws an error, but also throws a warning that causes problems. We need to remove the warning. ``` expect_error(genSpline( dt = dt,...

Changing subheader - remove author name

I just downloaded the latest version of the Beautiful Hugo theme - for the first time in a few years. I noticed a slight change in the appearance of the...

Create a longitudinal dataset is not just counting integers but reflects actual time points

4

A user identified a possible enhancement to the function `addPeriods`. Right now, periods can only be defined as integers ranging from $0$ to $n-1$, so that there are $n$ periods....

A while back, I created a [scenario](https://www.rdatagen.net/post/2022-08-30-expanding-the-possibilities-of-simulation-in-simstudy-with-customized-distribution-funcdtions/) that used a truncated distribution function in combination with a nonrandom distribution to create a flexible data generating process. However, I think recent...
