approximate calculation of size or cost
A careful guess about how big, how many, how long, or how much something will cost or be worth.
用法パターン：
an estimation of [amount/cost/size]
よくある間違い：
Learners sometimes confuse "estimation" with the verb "estimate". Use "estimation" as a noun ("make an estimation"), and "estimate" as a verb ("to estimate the cost"). Also, avoid saying *"do an estimation"*; "make" or "give" is more natural.

estimate (More common and slightly less formal; can be both noun and verb.)

対義語

personal judgment or opinion
What someone thinks or believes about how good, important, or right something or someone is.
用法パターン：
in [someone]'s estimation, [clause]

Learners sometimes say *"on my estimation"* instead of the correct phrase "in my estimation" when giving a personal judgment. Also, do not use it when you talk about a proven fact; it is used for personal views.
類義語
opinion (More general and common; does not suggest the careful weighing that "estimation" can imply.)
|
assessment (Suggests a more thorough or systematic judgment than "estimation".)
対義語
fact (Contrasts a personal judgment with something that is objectively true.)
|
certainty (Opposes the idea of a tentative or personal judgment.)

用法パターン：

類義語
esteem (Very close in meaning; used more often in formal or written English.)
|
regard (Slightly broader; may be less intense than "esteem" or "high estimation".)
対義語
disrespect (Shows a clear lack of respect, the opposite of high estimation.)
|

statistical or mathematical estimating process
In math, science, or engineering, the way to find an estimated value for something you do not know, using numbers or data.
用法パターン：
estimation of [parameter/value] using [method]
よくある間違い：
Learners may not realize that in technical texts "estimation" often refers to a formal method, not just a quick guess. In these contexts, it usually goes with words like "parameter", "model", or a named method such as "maximum likelihood".
類義語
estimation procedure (More explicit in technical writing; highlights the method used.)
|
inference (In statistics, can overlap when talking about drawing conclusions from data, but is broader than estimation alone.)
対義語
measurement (In technical fields, measurement finds an observed value directly, rather than inferring or estimating it.)
|
exact computation (Indicates that no approximation is involved, unlike in estimation.)

|maximum likelihood estimation
