te_stats_glm_logit-class function

Fit Models using logistic stats::glm

The classes and (internal) methods defined for using stats::glm to fit the logistic regression models. class

## S4 method for signature 'te_stats_glm_logit'
fit_weights_model(object, data, formula, label)

## S4 method for signature 'te_stats_glm_logit'
fit_outcome_model(object, data, formula, weights = NULL)

## S4 method for signature 'te_stats_glm_logit_outcome_fitted'
predict(
  object,
  newdata,
  predict_times,
  conf_int = TRUE,
  samples = 100,
  type = c("cum_inc", "survival")
)

Arguments

• object: Object to dispatch method on
• data: data.frame containing outcomes and covariates as defined in formula.
• formula: formula describing the model.
• label: A short string describing the model.
• weights: numeric vector of weights.
• newdata: Baseline trial data that characterise the target trial population that marginal cumulative incidences or survival probabilities are predicted for. newdata must have the same columns and formats of variables as in the fitted marginal structural model specified in trial_msm() or initiators(). If newdata contains rows with followup_time > 0 these will be removed.
• predict_times: Specify the follow-up visits/times where the marginal cumulative incidences or survival probabilities are predicted.
• conf_int: Construct the point-wise 95-percent confidence intervals of cumulative incidences for the target trial population under treatment and non-treatment and their differences by simulating the parameters in the marginal structural model from a multivariate normal distribution with the mean equal to the marginal structural model parameter estimates and the variance equal to the estimated robust covariance matrix.
• samples: Number of samples used to construct the simulation-based confidence intervals.
• type: Specify cumulative incidences or survival probabilities to be predicted. Either cumulative incidence ("cum_inc") or survival probability ("survival").

Functions

• fit_weights_model(te_stats_glm_logit): Fit the weight models object via calculate_weights on trial_sequence
• fit_outcome_model(te_stats_glm_logit): Fit the outcome model object via fit_msm on trial_sequence
• predict(te_stats_glm_logit_outcome_fitted): Predict from the fitted model object via predict on trial_sequence
