All distributions share the same latent variable η_{ij} = a + b_i with b_i = N(0, σ_r)
generate_data( a = 0, sigma_random = 0.5, n_random = 20, n_replicate = 10, nb_size = 1, b_size = 5, zero_inflation = 0.5 )
a |
the intercept of the latent variable |
sigma_random |
The standard error for the random effect σ_r |
n_random |
the number of random effect levels (groups) |
n_replicate |
the number of observation per random effect level |
nb_size |
the size parameter of the negative binomial distribution.
Passed to the |
b_size |
the size parameter of the binomial distribution. Passed to the
|
zero_inflation |
the probability the the observed value stems for the a point mass in zero |
The Poisson distribution uses λ = e^{η_{ij}}
The negation binomial distribution uses μ = e^{η_{ij}}
The binomial distribution uses π_{ij} = e^{η_{ij}}/(e^{η_{ij}}+ 1)
