Hello all,
I am getting status 5 for some analyses and am not sure why. I am including the code and output below. There are 4 clusters and 9 effects. Any idea what is causing it?
Thanks!
#### CODE
clustvar <-c(3.1,3.1,41.1,52.1,52.1,52.1,52.1,56.1,56.1)
effsize <-c(0.0370169,-0.04603249,0.25541281,0.20065009,0.18405043,0.12667322,0.21526454,0.01300073,-0.05304971)
samplvar <-c(0.01020408,0.01020408,0.01298701,0.01538462,0.01538462,0.01538462,0.01538462,0.0078125,0.0078125)
summary( meta3(y=effsize, v=samplvar,cluster=clustvar) )
### End Code
Output below
Call:
meta3(y = effsize, v = samplvar, cluster = clustvar)
