Specify
fixed effects
that are to be used to form interaction effects with the
Exon (Probeset) ID Variable
specified on the
General
tab. These are typically a subset of the
Fixed Effects
specified previously.
Distinct interaction effects are included in the
model
for each effect specified here. Significance of these interactions can be an indication of alternative splicing.
Caution
: Specifying many effects here can result in an overspecified model and nonestimable LSMeans. In addition, specifying effects with many levels can greatly increase computing time, especially for
transcript clusters
that have numerous
exons
.
