r - Lavaan 与 Mplus 中的增长曲线建模

Question

我想复制我在 M plus 8 中使用lavaan.

M加脚本：

TITLE:    First stab;
DATA:     FILE = dataLong.csv;
VARIABLE: 
   NAMES = PtIDNo weeklyscore baseline 6month SGstatus Txhalf rmssd1 rmssd2 sd1 sd2 BDIr1 BDIr2 BDIor ID Sess Sesslog;
   USEVAR = weeklyscore Sess SGstatus rmssd1 sd1 baseline 6month;
   CLUSTER = PtIDNo;
   MISSING = all (-99); 
   WITHIN = Sess;
   BETWEEN = SGstatus rmssd1 sd1 baseline 6month;
   USEOBSERVATIONS = Txhalf eq 1;
DEFINE: center rmssd1 sd1 baseline(grandmean);
ANALYSIS:   
   TYPE = TWOLEVEL RANDOM;
   ESTIMATOR = ml;
MODEL:
   %WITHIN%
   s|weeklyscore on Sess;
   %BETWEEN%
   s with weeklyscore;
   6month on baseline s SGstatus rmssd1 sd1;
OUTPUT:  
   tech1 tech3 sampstat standardized cinterval pat svalues;

拉文脚本：

firsthalfmodel.1 = "

i =~ 1*Sess0 + 1*Sess1 + 1*Sess2 + 1*Sess3 + 1*Sess4 + 1*Sess5 + 1*Sess6 + 
1*Sess7 + 1*Sess8 
s =~ 0*Sess0 + 1*Sess1 + 2*Sess2 + 3*Sess3 + 4*Sess4 + 5*Sess5 + 6*Sess6 + 
7*Sess7 + 8*Sess8 

# Regressions
6month~baseline+s+SG+sd_1+rmssd_1"

问题：

我可以像在 M pluslavaan中那样将斜率与每周得分相关联吗？
