Figure 4
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 “0.75” and “0.71,” 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 3” and “e 5.” Each circle has a right‑pointing arrow leading to its corresponding rectangle: “e 3” points to “A A F C 8,” and “e 5” to “A A F C 5.” The “F 2” oval node is positioned below “F 1.” From “F 2,” two right‑pointing arrows arise and connect to two rectangles arranged in a vertical series. These arrows are labeled “0.70” and “0.80,” and they connect from top to bottom to the rectangles labeled “P F H I 6” and “P F H I 8.” On the right of these rectangles, two ovals are arranged vertically and labeled from top to bottom as “e 10” and “e 15.” Each circle has a right‑pointing arrow leading to its corresponding rectangle: “e 10” points to “P F H I 6,” and “e 15” 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 “0.65” and “0.82,” 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 17” and “e 18.” Each circle has a right‑pointing arrow leading to its corresponding rectangle: “e 17” points to L E F H I 3,” and “e 18” 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 “0.76” and “0.74,” and they connect from top to bottom to the rectangles labeled “A A F C 7” and “A A F C 6.” On the right of these rectangles, two ovals are arranged vertically and labeled from top to bottom as “e 20” and “e 21.” Each circle has a right‑pointing arrow leading to its corresponding rectangle: “e 20” points to “A A F C 7,” and “e 21” to “A A F C 6.” From “F 1,” a double‑headed arrow labeled “0.58” points to “F 2.” From “F 1,” a double‑headed arrow labeled “0.46” points to “F 3.” From “F 1,” a double‑headed arrow labeled “0.85” points to “F 4.” From “F 2,” a double‑headed arrow labeled “0.26” points to “F 3.” From “F 2,” a double‑headed arrow labeled “0.33” points to “F 4.” From “F 3,” a double‑headed arrow labeled “0.42” points to “F 4.”Final adjusted model.
