attribute_classes function

Simulate all the Latent Attribute Profile $\mathbf{\alpha}_c$ in Matrix form

Generate the $\mathbf{\alpha}_c = (\alpha_{c1}, \ldots, \alpha_{cK})'$

attribute profile matrix for members of class $c$ such that $\alpha_{ck}$ ' is 1 if members of class $c$ possess skill $k$

and zero otherwise.

attribute_classes(K)

Arguments

• K: Number of Attributes

Returns

A $2^K$ by $K$ matrix of latent classes corresponding to entry $c$ of $pi$ based upon mastery and nonmastery of the $K$ skills.

## Simulate Attribute Class Matrix ----

# Define number of attributes
K = 3

# Generate an Latent Attribute Profile (Alpha) Matrix
