Good afternoon, I am attempting to replicate a published study using their supplied correlation matrix and means and standard deviations, and I keep getting the following error message after specifying this input: Data: FILE IS "matrix3_2014.txt"; TYPE IS CORR MEANS STDEVIATIONS ; NOBSERVATIONS = 122; variable: NAMES ARE V1-V6; USEVARIABLES ARE ALL; model: Y1 BY V1-V3; Y2 BY V4-V5; V6 on Y1 Y2; Y1 WITH Y2; *** ERROR One or more variables have a variance of zero. Variable Variance VOC 0.146 LSK 0.380 BURT 0.660 **WRAT 0.000 **LC 0.000 RC 0.889 Since this is summary data, why am I getting this error message? Thank you for your help! |

I apologize, I was trying to blind the variable names at the bottom. Those correspond to V1-V6. |

good news, I figured out my issue. For those who read this at a later time and wonder the same thing: try to use a full correlation matrix instead and specify FULLCORR. that fixed it for me, though there may have been another way to fix it using the partial matrix. |
