How to describe a scenario that is close to the real conditions

I am writing a technical paper that includes economic analysis. In one section, I need to give a justification for choosing interest rates used in the study. I am trying to say the interest rates were chosen according to the reports of the central bank of the country to make the results of the study reliable and closer to the real conditions.

I am looking for an elegant and academically acceptable phrase or word to describe this.

Solution 1:

Reliable is a good word, don't change it.

For the other part I was thinking of accurate which means:

agreeing with facts (Cambridge)

Accurate describes well noun like results, measurements, information.

Factual is close in meaning, but it is not very commonly used to describe results.

But since it is not a single word that you are looking for, you could also use expressions like:

agree with facts

or

be consistent with reality

I particularly recommend consistent which means:

acting or done in the same way over time, especially so as to be fair or accurate (OxfordL)

and

in agreement with other facts or with typical or previous behaviour, or having the same principles as something else (Cambridge)

So your sentence could be written as:

the interest rates were chosen according to the reports of the central bank of the country to make the results of the study reliable and consistent with reality/accurate.
