Calling fit will trigger the fitting of all statistical models which have been specified for the model. This will result in fits for each group - outcome - stat combination.

Usage

# S3 method for abaModel
fit(object, ...)

Arguments

object

aba model The aba model to be fitted.

...

additional parameters.

Value

abaModel

Details

Note that this function is identical to the generic aba_fit() function.

Examples

data <- adnimerge %>% dplyr::filter(VISCODE == 'bl')

model_spec <- data %>% aba_model() %>%
  set_groups(everyone()) %>%
  set_outcomes(ConvertedToAlzheimers, CSF_ABETA_STATUS_bl) %>%
  set_predictors(
    PLASMA_ABETA_bl, PLASMA_PTAU181_bl, PLASMA_NFL_bl,
    c(PLASMA_ABETA_bl, PLASMA_PTAU181_bl, PLASMA_NFL_bl)
  ) %>%
  set_stats('glm')

model <- model_spec %>% aba_fit()
#> [1] "ConvertedToAlzheimers ~ PLASMA_ABETA_bl"
#> [1] "ConvertedToAlzheimers ~ PLASMA_PTAU181_bl"
#> [1] "ConvertedToAlzheimers ~ PLASMA_NFL_bl"
#> [1] "ConvertedToAlzheimers ~ PLASMA_ABETA_bl + PLASMA_PTAU181_bl + PLASMA_NFL_bl"
#> [1] "CSF_ABETA_STATUS_bl ~ PLASMA_ABETA_bl"
#> [1] "CSF_ABETA_STATUS_bl ~ PLASMA_PTAU181_bl"
#> [1] "CSF_ABETA_STATUS_bl ~ PLASMA_NFL_bl"
#> [1] "CSF_ABETA_STATUS_bl ~ PLASMA_ABETA_bl + PLASMA_PTAU181_bl + PLASMA_NFL_bl"
