Figure 6
The figure shows four latent variables, each represented by an oval node with the following labels: “F 1,” “F 2,” “F 3,” and “F 4.” The “F 1” oval node is positioned at the top. From “F 1,” two right‑pointing arrows arise and connect to two rectangles arranged in a vertical series. These arrows are labeled “0.72” and “0.78,” and they connect from top to bottom to the rectangles labeled “A A F C 1” and “L E F H I 8.” On the right of these rectangles, two ovals are arranged vertically and labeled from top to bottom as “e 7” and “e 10.” Each circle has a right‑pointing arrow leading to its corresponding rectangle: “e 7” points to “A A F C 1,” and “e 10” to “L E F H I 8.” The “F 2” oval node is positioned below “F 1.” From “F 2,” three right‑pointing arrows arise and connect to three rectangles arranged in a vertical series. These arrows are labeled “0.76,” “0.73,” and “0.75,” and they connect from top to bottom to the rectangles labeled “P F H I 6,” “P F H I 7,” and “P F H I 8.” On the right of these rectangles, three ovals are arranged vertically and labeled from top to bottom as “e 3,” “e 4,” and “e 5.” Each circle has a right‑pointing arrow leading to its corresponding rectangle: “e 3” points to “P F H I 6,” “e 4” to “P F H I 7,” and “e 5” to “P F H I 8.” The “F 3” oval node is positioned below “F 2.” From “F 3,” two right‑pointing arrows arise and connect to two rectangles arranged in a vertical series. These arrows are labeled “0.70,” and “0.77,” and they connect from top to bottom to the rectangles labeled “L E F H I 3,” and “L E F H I 4.” On the right of these rectangles, two ovals are arranged vertically and labeled from top to bottom as “e 12,” and “e 13.” Each circle has a right‑pointing arrow leading to its corresponding rectangle: “e 12” to “L E F H I 3,” and “e 13” to “L E F H I 4.” The “F 4” oval node is positioned below “F 3.” From “F 4,” two right‑pointing arrows arise and connect to two rectangles arranged in a vertical series. These arrows are labeled “0.74,” and “0.72,” and they connect from top to bottom to the rectangles labeled “A A F C 8” and “A A F C 5.” On the right of these rectangles, two ovals are arranged vertically and labeled from top to bottom as “e 17” and “e 18.” Each circle has a right‑pointing arrow leading to its corresponding rectangle: “e 17” points to “A A F C 8,” and “e 18” to “A A F C 5.” From “F 1,” a double‑headed arrow labeled “0.65” points to “F 2.” From “F 1,” a double‑headed arrow labeled “0.50” points to “F 3.” From “F 1,” a double‑headed arrow labeled “0.88” points to “F 4.” From “F 2,” a double‑headed arrow labeled “0.30” points to “F 3.” From “F 2,” a double‑headed arrow labeled “0.57” points to “F 4.” From “F 3,” a double‑headed arrow labeled “0.48” points to “F 4.”Final adjusted model.
