刘老师您好，请问做完面板估计之后，怎么将预测值和实际值画在图上。听说应该用solve，但显示
Model: Untitled
Date: 03/27/14   Time: 02:17
Sample: 1974Q1 2013Q4
Solve Options:
        Dynamic-Deterministic Simulation
        Solver: Broyden
        Max iterations = 5000, Convergence = 1e-08

Parsing Analytic Jacobian:
0 derivatives kept, 0 derivatives discarded

Scenario: Baseline
Solve begin 02:17:18
        1974Q1   NA generated for LREER01_AUS
Solve terminated - Unable to compute due to missing data  in "LREER01_AUS  = @COEF(1) * LTOT01_AUS  + @COEF(2) * LPRO01_AUS  + @ ...

貌似是因为我的数据域缺失值，但即使调整到不含缺失值得样本区间也不行。请问应该怎么做？
