  1. ¿Cómo surge un valor de dependencia parcial de una sola característica en un punto de la cuadrícula?
    • Average observed feature values without model predictions
    • Fit a new model using only the selected column
    • Average model predictions after setting that feature to the grid value
    • Count how many examples have that exact value
  2. ¿Qué aporta una pantalla ICE más allá de un promedio de dependencia parcial?
    • A causal effect estimate
    • A prediction curve for each individual example
    • A guarantee that features are independent
    • A new model trained for every row
  3. Las líneas ICE se abren en abanico a medida que cambia una característica. ¿Qué sugiere esto?
    • The average represents every example's response equally well
    • The selected feature has the same additive response for every case
    • Only the baseline prediction levels differ while curve shapes remain parallel
    • The average may hide heterogeneous model responses
  4. ¿Por qué los predictores correlacionados pueden hacer que un gráfico de dependencia parcial sea engañoso?
    • Substitution can create unrealistic feature combinations
    • Averaging automatically removes all feature dependence
    • Keeping other inputs fixed guarantees a valid intervention
    • Restricting a feature to its observed range guarantees every joint combination is realistic
  5. ¿Qué tipo de afirmación respalda más directamente una curva de dependencia parcial?
    • The causal effect of changing a feature
    • The model's calibration on every subgroup
    • How this fitted model's average output varies under the plot calculation
    • The distribution of true labels at each feature value
  6. For a classifier, what should a report specify about the plotted output?
    • Only whether a classifier exceeds 50% accuracy
    • Class and output scale, such as probability or decision score
    • Only the ranking of feature variances
    • Only whether the predictions were rounded to labels
  7. Which alternative may reduce extrapolation concerns under dependent features by estimating local changes?
    • A marginal plot without checking confounding inputs
    • An uncentered ICE plot that uses the same unrestricted substitutions
    • A global feature ranking based only on training coefficients
    • Accumulated local effects
  8. Centered ICE is useful for comparing what across examples?
    • Differences in curve shape after subtracting a reference prediction
    • Only differences in the original prediction baselines
    • The distribution of observed outcomes without model predictions
    • Causal treatment effects for each example
