M % addProviderTiles("Stamen.Watercolor") %>%įabricatr is part of the DeclareDesign suite of packages from Graeme Blair and his colleagues for “formally ‘declaring’ the analytically relevant features of a research design”. The off diagonal elements specify the joint probabilities that V1 and V2 are both one. In the simple example below M specifies the probability that the random variable V1 will be a 1, while M does the same for variable V2. You can begin by setting up a matrix, M, of “common probabilities”.

Suppose you want to create a matrix whose columns are draws from binary random variables. The package does one really nice trick: it provides multiple ways to create columns of binary random variables that have a pre-specified correlation structure. Andreas Weingessel, and Kurt Hornik that goes back to 1999 and still gets about twenty-five downloads a day. Here are a few of R package that ought to be helpful in nearly every project where you need to manufacture fake data.īindata is an “oldie but goodie” from R Core members Friedrich Leisch. Building a data set that reproduces some of the statistical properties of the real data while passing the eyeball test for being convincing may make all the difference in communicating your ideas.

Carefully constructed fake data may be helpful in testing the limits of an algorithm or analysis.Having a generative model might really simplify your analysis, and knowing that you don’t have one may be critical too. For example, when you may have data that comes from some kind of arrival process, it may be helpful to simulate Poisson arrivals to see if counts and arrival time distributions match with your data set. Simulation is part of exploratory data analysis.
