Hi This is my model below. I have a low residual variance on ftconfs. How can I set this to 0? i s | dtconfs@0 etconfs@1 ftconfs@2; s (slope); i with s@0; %c#1% [i*1.3]; %c#2% [i*3.5]; MODEL CONSTRAINT: slope > 0; |
|
|
If you want to fix s at zero, say in the MODEL command: s@0; |

Thanks Linda, isn't it the residual variance on ftconfs that I want to set at zero? |
|
|
Then you would say ftconfs@0; |

Hi, My growth model wont run unless I set the residual variances to zero. When I try to let them be estimated freely (see below) the model will not run. Do you know why? ANALYSIS: TYPE = RANDOM; ESTIMATOR=MLR; H1ITERATIONS=20000; ITERATIONS=20000; COVERAGE=0; ALGORITHM=INTEGRATION; MODEL: !define level factors i s q | WB12 AT TS0 WB14 AT TS1 WB16 AT TS2; !means [WB12-WB16@0]; [i*12.226]; [s*-0.199]; [q*0.115]; !variance and covariance i*4.829; s*8.856; q*; i WITH s*; i WITH q*; s WITH q*; !specific variance WB12*1.983; WB14*2.584; WB16*1.236; |
