Strategy Oracle Sets

Description

Pre-generated strategy matrices used in simulation studies to verify recovery.

Format

An array with varying numbers of items (J), traits (K), and strategies (S).

Specifically:

• strategy_oracle_k3_j20_s2: 20 items, 3 traits, and 2 strategies.

• strategy_oracle_k3_j30_s2: 30 items, 3 traits, and 2 strategies.

• strategy_oracle_k3_j40_s2: 40 items, 3 traits, and 2 strategies.

• strategy_oracle_k3_j50_s2: 50 items, 3 traits, and 2 strategies.

• strategy_oracle_k4_j20_s2: 20 items, 4 traits, and 2 strategies.

• strategy_oracle_k4_j30_s2: 30 items, 4 traits, and 2 strategies.

• strategy_oracle_k4_j40_s2: 40 items, 4 traits, and 2 strategies.

• strategy_oracle_k4_j50_s2: 50 items, 4 traits, and 2 strategies.

Details

Each entry in a strategy is denoted by either 1, if the item uses the skill under strategy s, or 0, if the item does not use the skill under strategy s.

Note: Each matrix in the strategy was generated independently under the criterion for a strictly identifiable Q matrix.
