Hi,
I am trying to impute my data file that has participants over three days of
sampling and two predictors. I set up my data in SPSS with like this:
ID Time predictor1 predictor2 measure 1 measure 2 measure 3 measure
4
101.0 1.0 10.0 8:58 1.097 -0.492
9.680 -0.095
101.0 2.0 10.0 9:00 2.399 0.299
13.202 -0.801
101.0 3.0 10.0 8:15 1.636 -0.316
20.445 -0.931
102.0 1.0 27.0 7:07 3.903 0.473
31.106 -0.916
102.0 2.0 27.0 7:21 3.797 0.473
31.994 -0.966
102.0 3.0 27.0 7:34 2.829 0.227
29.497 -0.958
I tried using the time series cross sectional option using time as ts and ID
as cs. I put the polynomials time as 1 (although I'm really not sure about
that) and used an EM prior of 4. At the bottom of my AmeliaView it says I
have 381 observations and 9 variables, which does not exceed the p(p+3)/2
formula yet I am still getting error code 34:
Amelia Error Code: 34
The number of observations in too low to estimate the number of
parameters. You can either remove some variables, reduce
the order of the time polynomial, or increase the empirical prior.
You have recieved an error. You can close this window and reset
various options to correct the error.
I'm not sure what I'm doing wrong! Any help would be greatly appreciated!
Thank you,
Sivan
