Hi, When running a growth curve model, I got the error that variance is greater than the maximum allowed of 1000000. I divided my outcome variables (rates of STDs) by a constant of 2 and that fixed the problem. My questions are: 1. When interpreting the mean of the intercept do I need to multiply it by 2? 2. When interpreting the mean of the slope, do I need to multiply by 2? Thank you! Diana |

Instead of bothering with multiplication of estimates, why don't you instead re-define the variable? For instance, if a variable is recorded in centimeters and you have a variance of 1000000 (6 zeros), you can divide the variable by 100 - that is, define the variable in meters instead - which would cut down the variance by 100*100, which gives you a variance of 100 instead of the original 1000000. Dividing by 2 has no substantive meaning. |
