No matter how accurate the input data are, if the model is accurate, the results are accurate.

Question restatement: The claim is that no matter how accurate the input data are, if the model is accurate, the results are accurate. 
Option 1: True. This would mean that model accuracy alone guarantees correct results regardless of input data quality. In practice, data quality and model accuracy interact; even a highly accurate model cannot compensate for inaccurate or biased inputs, and data issues can propagate through the model, leading to flawed outputs. Misleading, incomplete, or corrupted inputs can produce misleading results even when the model itself is well-calibrated, so this statement overstates the protective effect of model accuracy.
Option 2: False. This option correctly challenges the idea by emphasizing the dependency between data quality and model output. If input data are inaccurate, biased, or noisy, the model’s results can be compromised despite the model’s own accuracy. The reasoning relies on the foundational principle that data quality is a prerequisite for reliable modeling; good model performance cannot fix data problems. 
Additional nuance: In real-world modeling, both data quality and model validity must be addressed together. A model might be accurately following flawed data patterns (overfitting to spurious signals) or be robust to certain noise but still fail when inputs degrade, demonstrating that input accuracy and model accuracy are both essential for trustworthy results.
In summary, the statement conflates two separate sources of error—data quality and model behavior—and ignores how they interact to determine final results. The correct framing is that accurate results hinge on both accurate data and an appropriate, well-specified model.

Validation of the model is to check the logic of the model and to determine if all the calculations, steps, and procedures are done correctly in the model.

Once your stochastic model is constructed, how do you check that it is working properly?

Consider the validation set approach. We estimate the model on the training set, and make predictions on the validation set.

Models need to be validated:

Models selected by automated variable selection techniques do not need to be validated since they are ‘optimal’ models.
