Dear All,
I am using the following commands to generate a given dataset:
a <-c(0.348,0.007,0.503,0.58,0.21)
cov
<-c(0.0448,0,0,0,0,0.0001,0.0001,0,0,0,-0.0055,-0.0005,0.0495,0,0,0.0218,0.0009,-0.0253,0.1103,0,-0.0102,-0.0007,0.00631,0.0067,0.0132)
b <-matrix(cov,nrow=5, ncol = 5, byrow = TRUE,dimnames = NULL)
g <-mvrnorm(10000,a,b)
is there a way to place limits on the simulated values so that they all remain
positive? I am simulating biological variables that should never be 0.
thnaks,
Andras
