  sigma = numeric(0),
  r_squared = numeric(0),
  adj_r_squared = numeric(0),
  f_statistic = integer(0),
  f_p_value = integer(0),
  logLik = numeric(0),
  AIC = numeric(0),
  BIC = numeric(0),
  nobs = numeric(0),
  df_residual = numeric(0),
  df_model = numeric(0),
  statistic = integer(0),
  p_value = integer(0),
  call = NULL,
  term_expressions = NULL
)

Details

This class is not called directly by users. It is created internally by [lm_sql()] and returned as the model object. It stores fitted coefficients, standard errors, t-statistics, p-values, and model-level summaries (R-squared, F-statistic, AIC, BIC, etc.). The `term_expressions` property holds named R expressions for each predictor, which are used by the [orbital.lm_sql_result()] method to generate in-database prediction expressions.
