I'm completely stumped and seem to be going around for 2 days in the wrong
circles. Here's what I have in 2 dataframes:
dim(params.data); head(params.data, n=2)
[1] 284 6
itema1a2 b1 b2 c
11 0.6671587 0.9588642 -3.5 -3.437961 0.2
22 1.1296298 1.4899307 -3.5
Better to not use c as a variable name. It's such a useful function
name.
This is what I would have tried:
col3 - expand.grid(item=params.data$item, examinee=examinees.data
$examinee)
col3$p_val - p( c( params.data[ col3[item], c(a1, a2, b1,
b2, c) ],
examinees.data[
2 matches
