Random Intercept, No slope - Plots |

Hi, I have been trying to run a growth model, with random intercepts but no slope (or a slope of 0) for individuals with varying times of observation using the following key bits of syntax. It runs fine, but when I look at Plots>Observed individual values and ask for individually-fitted curves, some of my lines have a slope. Am I incorrectly specifying how to get a random intercept with no slope, or is the plot showing me something different? TSCORES = time11-time63; IDVARIABLE IS id; ANALYSIS: ESTIMATOR = MLR; TYPE = RANDOM; PROCESSORS = 4; MODEL: i | exppos11-exppos63 AT time11-time63; PLOT: TYPE = PLOT1 PLOT2 PLOT3; SERIES = exppos11-exppos63(*); |
|

SERIES with * uses time scores of 1, 2,, etc. There isn't an automatic plot with AT. You have to plot it outside Mplus. |

Ok, so just to clarify... Am I right in understanding that my model results are giving me what I expected and that any factor scores I save using the above specification are giving me the intercept for each individual with a slope of 0 (i.e. no slope)? |
