a posterior class

USAGE SUMMARY

The phrase "a posterior class" is correct and usable in written English.
It can be used in contexts related to classification, particularly in philosophy or statistics, where it refers to a class defined based on observed data or outcomes. Example: "In our analysis, we categorized the results into a posterior class to better understand the implications of the findings."

Specifically, a class membership was generated for each individual from a multinomial distribution using the posterior class probability, and then a Cox model was fit to assess the effects of latent classes on POAG.

BMC Medical Research Methodology

To select the best IRES predictions, we used a simple procedure that consisted of multiplying the posterior class probability [ 39] (the probability that a prediction is an IRES based on SVM output) of each prediction by its corresponding orthologous group enrichment p-value.

BMC Genomics

Entropy is a summary statistic based on the posterior class membership probabilities that evaluates the quality of the classification in terms of the separation of the latent classes.

American Journal of Epidemiology

Class sizes were calculated on the basis of the estimated posterior class membership probabilities (the probability of a subject's belonging to a given class conditional on his or her observed response values).

American Journal of Epidemiology

The modifier screens using EMS produced similar phenotypes to those observed in the P-element screen (Figure 4) and additionally produced a "posterior crossveinless" class (14/27 modifiers; Figure S2).

Plosone

An alternative approach to the joint latent class model could be a two-stage approach where a latent class mixed model would be estimated first using only repeated measures of MMSE to identify the subpopulations and then a survival model would be estimated in each posterior class.

European Journal of Epidemiology

In males, subjects in class A (52.8% of study members using estimated posterior class membership probabilities) reported almost entirely low rates of walking during the day at age 36 years, while in class B (47.2%), subjects reported middle or high rates.

American Journal of Epidemiology

Congruent with their phylogenetic position, acoels appear to possess only a subset of the Hox genes found in protostomes and deuterostomes, namely one anterior, one central and one posterior class gene, as well as an ortholog of the posterior ParaHox gene Cdx [ 45].

BMC Biology

We propose a parametric family of loss functions that provides accurate estimates for the posterior class probabilities near the decision regions.

Neurocomputing

As we saw with its treatment of posterior class probabilities, the mixture believes each observation comes from a single component, while averaging over weak learners or hidden layers may be relevant to a more admixed sample.

Expert writing Tips

Best practice

When using "a posterior class", ensure the context clearly indicates that the class is defined based on observations or derived data. It's most appropriate in technical or philosophical discussions.

Common error

Avoid using "a posterior class" when the classification is based on predefined criteria or assumptions, not on empirical evidence. "A posterior class" implies a classification after observation, not before.

Linguistic Context

The phrase "a posterior class" functions as a noun phrase. According to Ludwig AI, it is used in contexts related to classification, particularly in philosophy or statistics, where it refers to a class defined based on observed data or outcomes.

Ludwig's WRAP-UP

In summary, the phrase "a posterior class" is a grammatically correct noun phrase primarily used in scientific and technical contexts. According to Ludwig AI, it refers to a class defined based on observed data or outcomes. While its usage is relatively rare, it's important to use it accurately, ensuring the classification is genuinely derived from empirical evidence and not from predefined assumptions. Consider alternatives like "a subsequent class" or "a resulting category" depending on the intended meaning.

More alternative expressions

Phrases that express similar concepts, ordered by semantic similarity:

a subsequent class

Replaces 'posterior' with 'subsequent', emphasizing temporal sequence rather than a derived classification.

a resulting category

Focuses on the outcome of a classification process, using 'resulting' instead of 'posterior'.

a derived group

Highlights that the group is obtained through a derivation or calculation, similar to 'posterior'.

an inferred class

Emphasizes that the class is determined through inference or deduction.

a classified subset

Replaces "class" with "subset" focusing on it as part of a bigger grouping

a latent class

Focuses on a class that's hidden or not directly observable but inferred from data.

an identified cluster

Highlights the grouping aspect, using 'cluster' instead of 'class'.

a probabilistic class

Underlines that the class assignment is based on probabilities.

a diagnostic category

Focuses on the categorization for diagnostic purposes.

a data-driven class

Highlights that the classification is based on data analysis.

FAQs

How is "a posterior class" used in statistical analysis?

In statistical analysis, "a posterior class" typically refers to a group defined based on the results of a statistical model or analysis. This contrasts with classes defined a priori, before the analysis takes place.

What's the difference between "a posterior class" and "a latent class"?

"A posterior class" is a class defined after observing data or outcomes, while "a latent class" refers to a hidden or unobserved class inferred from data using statistical models.

In what fields is the term "a posterior class" commonly used?

The term "a posterior class" is commonly used in fields such as statistics, machine learning, and philosophy, particularly in discussions of Bayesian inference and classification problems.

What can I say instead of "a posterior class"?

Depending on the context, you can use alternatives such as "a subsequent class" or "a resulting category". The best choice depends on the specific nuance you want to convey.
