ARI function

Adjusted Rand Index (ARI)

Compute the Adjusted Rand Index (ARI) between the true latent variables and the estimated latent variables

ARI(z, hat.z)

Arguments

• z: Matrix of size $Q \times n$ with entries = 0 or 1 : 'true' latent variables
• hat.z: Matrix of $Q \times n$ with 0<entries<1 : estimated latent variables

Examples

z <- matrix(c(1,1,0,0,0,0, 0,0,1,1,0,0, 0,0,0,0,1,1), nrow = 3, byrow = TRUE)
hat.z <- matrix(c(0,0,1,1,0,0, 1,1,0,0,0,0, 0,0,0,0,1,1), nrow = 3, byrow = TRUE)
