## S3 method for class 'trim'
wald(x)

Arguments

• x: TRIM output structure (i.e., output of a call to trim)

Returns

A model-dependent list of Wald statistics

Examples

data(skylark)
z2 <- trim(count ~ site + time, data=skylark, model=2)
# print info on significance of slope parameters
print(z2)
z3 <- trim(count ~ site + time, data=skylark, model=3)
# print info on significance of deviations from linear trend
wald(z3)
