assumption of independency

USAGE SUMMARY

The phrase "assumption of independency" is not correct; the correct term is "assumption of independence." You can use it in contexts related to statistics, research, or any situation where the independence of variables or events is being discussed.
Example: "The assumption of independence is crucial for the validity of the statistical tests we are applying."

Unfortunately, some of the multivariate statistical procedures used in the present study rely on the assumption of independency of observations.

Plosone

Linear mixed models were used because the assumption of independency of observations was violated.

BMC Sports Science, Medicine and Rehabilitation

We sought to include in the statistical analyses only the calendar date of the first hospital admission of any given PUD crisis per patient, to adhere to the statistical assumption of independency of observations.

BMC Gastroenterology

Of most concern to us was the analysis of data by analysis of covariance (ANCOVA), mainly because the ANCOVA-inherent assumption of independency of the dependent variable (i.e., total number of eggs) is violated.

Environmental Health Perspectives

It confirms the finding of the present study, that in a population-based series the assumption of independency of loss to follow-up and death was reasonable, so that calculation of survival by the actuarial method without adjusting for losses to follow-up is likely to have resulted in no material bias in the estimates.

First, we used the external data on income source at time t, as knowing this information makes the assumption of conditional independency between the MCS value and missingness more plausible.

Clinical Epidemiology

The major limitation of the traditional MCA is its assumption that a system is always in a steady state, i.e. the assumption of linearity and independency (Fig 6).

BMC Systems Biology

Using the independency assumption of the sources, algebraic operations, Van Der Monde matrix properties, and an inverse Fourier transform, the authors successfully generate a signal of shifted Diracs with the required time delays, see Figure4. Figure 4 Blind estimation of time delays, τ 1 = 15 τ 2 = 35 and τ 3 = 55, the sources signals are three ARMA signals.

EURASIP Journal on Advances in Signal Processing

However, the orthogonality assumption of PCA and the statistical independency assumption of ICA place methodological constraints on biological signals.

BMC Systems Biology

The two scales and the higher order summary scale were shown to fulfil model expectations, including assumptions of unidimensionality, local independency and an absence of differential item functioning.

Health and Quality of Life Outcomes

One main assumption of latent class models is conditional independency of the methods being tested, which in our case might be violated because correlation exists between the outputs of different pipelines.

Expert writing Tips

Best practice

Always use the grammatically correct term "independence" instead of "independency" in formal writing and statistical contexts.

Common error

Avoid using "independency" as a noun. It's often a misspelling or incorrect usage of "independence".

Linguistic Context

The phrase "assumption of independency", while intending to express a condition where events or variables do not influence each other, is grammatically flawed. Ludwig AI points out that the correct form is "assumption of independence".

FAQs

What is the correct way to refer to the assumption that events are unrelated?

The correct phrase is "assumption of independence", not "assumption of independency". The term "independency" is not standard English in this context.

In statistical analysis, why is the assumption of independence important?

The assumption of independence is crucial because many statistical tests rely on it. Violating this assumption can lead to inaccurate results and invalid conclusions. You might need to explore alternative approaches if your data doesn't meet this "assumption of independence".

What are some alternatives to saying "assumption of independency"?

Instead of "assumption of independency", you can say ""assumption of independence"", "independence assumption", or "presumption of independence."

How does the violation of the assumption of independence affect statistical models?

When the assumption of independence is violated, the statistical model's validity is compromised. This can lead to biased estimates, incorrect p-values, and unreliable predictions. Consider using models that account for dependencies, such as mixed models or time series analysis, if you suspect a violation.
