Within-subjects 2×2 design with dichotomous response data
Description
This generic synthetic long-format data set has a dichotomous response Y
and two factors X1
and X2
. The response has categories {yes, no}
.
Factor X1
has levels {a, b}
, and factor X2
has levels
{c, d}
. It also has a PId
column for a participant identifier.
Participant identifiers are repeated across rows.
Format
A data frame with 60 observations on the following 4 variables:
- PId
a participant identifier with levels
"1"
..."15"
- X1
a within-subjects factor with levels
"a"
,"b"
- X2
a within-subjects factor with levels
"c"
,"d"
- Y
a dichotomous response with categories
"yes"
,"no"

ws2$Y = factor(ws2$Y, levels=c("yes","no"))
ws2$X1 = factor(ws2$X1)
ws2$X2 = factor(ws2$X2)
contrasts(ws2$X1) <- "contr.sum"
contrasts(ws2$X2) <- "contr.sum"
m = glmer.mp(Y ~ X1*X2 + (1|PId), data=ws2)
Anova.mp(m, type=3)
