marginal definition and meaning

These are the figurative uses for marginal, which comes from the Latin word margo “edge.” Literally, the word is used with things on a border. When you scribble words in the blank edges of your textbook pages, those notes are marginal.

When you drive around the block to park your car for a concert or event, you can keep driving around the block waiting for that perfect, free, on-street parking spot to come available. Or, you can weigh the alternative of spending $10 for a paid parking lot spot. What matters is what you do in the next minute, ten minutes, hour, or day. The marginal cost of finding a parking space could be only $10; or it could be another hour of driving around hoping for a free spot to open up just as you are in position to grab it. If you already spent an hour searching for a great parking spot, you may well do better to let that memory go. Thinking at the margin means to let the past go and to think forward to the next hour, day, year, or dollar that you expend in time or money. What’s better for you now or in the next few minutes?

Marginal definition

Help support Wordnik (and make this page ad-free) by adopting the word marginal. Adjective Of, relating to, located at, or constituting a margin, a border, or an edge. “Mean” could mean just any mean, e.g. the mean of all right handed men in the example of user28. By saying “mean of factor A” you should mean the mean of all levels of factor A, but you could mean the mean of one level of factor A. Using the term “marginal mean of factor A” makes it unambiguously clear what you mean.

This yields the same expression, TR (Q +1) − TR , as the marginal revenue. Adjective Barely within a lower standard or limit of quality. Then a table can be re-constructed to some extent using the text which refers to such things as ‘grand means’, ‘marginal means’ etc. I am guessing the phrase ‘marginal mean’ is a literary convention to signal what we are talking about. In a similar vein you could argue that why use the term ‘sample average’ when ‘average’ is sufficient.

What is another word for marginal?

It’s the additional cost or benefit that derives from a very small change. For example, if you increase your saving by $1, what would be the marginal benefit? The marginal benefit would thus be the sum of the 5 cents in interest plus the 2 cents in feelings of additional security, or $0.07 per additional dollar saved. If you plot a curve between the benefits and costs, the slope is .07. Many R packages advertise their ability to compute “marginal effects.” However, most of them do not actually compute marginal effects as defined above. Instead, they compute “adjusted predictions” for different regressor values, or differences in adjusted predictions (i.e., “contrasts”). The rare packages that actually compute marginal effects are typically limited in the model types they support, and in the range of transformations they allow (interactions, polynomials, etc.).

• The marginal area at the edge of the salt-marsh has its own plants.
• If you’re making a table, you may want to make it clear if the counts are totals or means.
• This can be applied to empirical distributions to also apply to things like tables of discrete (categorized/binned) observations, for example.
• It’s great to have a plot of marginal means, but how can I add SD or SE to that plot.
• “quality or state of being marginal,” 1849, from marginal + -ity.
• “Mean” could mean just any mean, e.g. the mean of all right handed men in the example of user28.
• Based on your description, it sounds like time ought to be categorical anyway, as the three time points have qualitative meanings.

Would be great if you could explain why the means differ. Likewise, if you have other factors in the model, if all those factors are balanced, the estimated marginal means will be the same as the observed means you got from descriptive statistics.

The first known use of marginal was

Add marginal to one of your lists below, or create a new one. These examples are from corpora and from sources on the web. Any opinions in the examples do not represent the opinion of the Cambridge Dictionary editors or of Cambridge University Press or its licensors.

Hi Lora, if I’m understanding your question correctly, then yes, you need to include B in the model. It turns out that curriculum A has slightly older kids and a higher mean math score than curriculum B. Observed what does the word marginal mean means for each curriculum will not account for the fact that the kids who received that curriculum were a little older. Marginal means will give you the mean math score for each group at the same age.

Of a value, or having a characteristic that is of a value, that is close to being unacceptable or leading to exclusion from a group or category. If the offensive player had initiated more than marginal contact, an offensive foul would be the correct call. From wordnet.princeton.edu, not affiliated with etymonline. Find the annual revenue when 1,500,000 barrels of beer are sold.

But you need to see the means and their standard errors to interpret the results. The difference in those means is what measures the effect of the factor.

To calculate marginal effects we need to take derivatives of the regression equation. This can be challenging to do manually, especially when our models are non-linear, or when regressors are transformed or interacted. Computing the variance of a marginal effect is even more difficult. https://business-accounting.net/ Marginal MeanAdjusted predictions of a model, averaged across a “reference grid” of categorical predictors. ContrastA difference, ratio, or function of adjusted predictions, calculated for meaningfully different predictor values (e.g., College graduates vs. Others).

Pertaining to changes resulting from a unit increase in production or consumption of a good. Grids using even larger voltages are now being constructed, but will probably make only a marginal improvement in costs. When Europe’s electricity markets are tight, the marginal wholesale price of power can be set by generation from comparatively expensive gas or coal plants. If that assumption is true, it’s inefficient to report separate estimates of the same population variance. So rather than report the variance separately for each group mean, it uses the average variance of all the groups.

American Dictionary

Marginal in economics means having a little more or a little less of something. It refers to the effects of consuming and/or producing one extra unit of a good or service. Marginal benefit is the change in total private benefit from one extra unit.

Differences in body weight are typical across a season for most people, and similar to a postseason break, your body will normalize once you’ve returned to full training.
