ARI {ppsbm}

Adjusted Rand Index (ARI)

Description

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

Usage

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)

ARI(z, hat.z)
