Algorithm 1

Obtaining latent variable estimates.

	Input: Strategy indicators sin and tin
	Output: Estimated value of latent variable
	Initialization: When m = m0,  = 1, otherwise  = 0
	Step 1: is used to obtain and
	Step 2: is obtained through multiple regression.
	Step 3: is used to obtain and
	Step 4: is obtained through multiple regression.
	Steps 1–4 should be repeated in a loop until the iteration accuracy is met.
