Latin Hypercube Sampling when parameters are defined according to specific probability distributions
...e using the lhs library, then I will try using the pse library. Generally when you have a package specific question, you should try to contact the package maintainer first. set.seed(1) # I don't think your model has only one parameter, so I will include multiple input_parameters <- c("dispersal_distance", "temperature", "pressure") N <- 50 exponential_rate <- 1/30 library(lhs) X <- randomLHS(N, length(input_parameters)) dimnames(X) <- list(NULL, input_parameters) # X is now a uniformly distributed Latin hypercube head(X) hist(X[,1], breaks=5) hist(X[,2], break...
