`summary` functions take the output and summarize it.
# S3 method for cate
summary(object, ..., significance_level = 0.05)
an output object
arguments passed on to the function
Numeric scalar between 0 and 1, inclusive, representing the significance level for the chi-square test. The test is used to determine whether at least one of the coefficients (except the intercept) is not equal to 0. Default is 0.05
Currently, observed densities (class: obs), estimates (class: est) and heterogeneity estimates (class: cate) are supported by this function.
