init3ordered function

Initial components from the Trivariate Moment Decomposition algorithm

The function is utilised from the function tuckerordered to compute the initial components for each of the three ordered categorical variables.

init3ordered(x, p, q, r, x0)

Arguments

• x: The three-way contingency table.
• p: The number of components of the first mode.
• q: The number of components of the second mode.
• r: The number of components of the third mode.
• x0: The original three-way contingency table.

Returns

The initial components for each of the three categorical variables.

• a: The initial component derived from the Trivariate Moment Decomposition for the first mode.

• b: The initial component derived from the Trivariate Moment Decomposition for the second mode.

• cc: The initial component derived from the Trivariate Moment Decomposition for the third mode.

• x: The three-way contingency table.
