### Usage

    sType(object)

    ## S4 method for signature 'deFit'
    sType(object)

### Arguments

`object` | `S4 object`: `deFit`

### Value

### Examples

    # import data
    library(splines)
    data(kidney)
    age <- kidney$age
    sex <- kidney$sex
    kidexpr <- kidney$kidexpr
    cov <- data.frame(sex = sex, age = age)

    # create models
    null_model <- ~sex
    full_model <- ~sex + ns(age, df = 4)

    # create deSet object from data
    de_obj <- build_models(data = kidexpr, cov = cov, null.model = null_model,
    full.model = full_model)

    # run fit_models to get model fits
    de_fit <- fit_models(de_obj)

    # extract the statistic type of model fits
    stat_type <- sType(de_fit)
