Outliers and Influential Points01:08

Outliers and Influential Points

6.7K
An outlier is an observation of data that does not fit the rest of the data. It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes (for example, writing down 50 instead of 500), while others may indicate that something unusual is happening. Outliers are present far from the least squares line in the vertical direction. They have large "errors," where the "error" or residual is the...

Quantifying and Rejecting Outliers: The Grubbs Test01:02

Quantifying and Rejecting Outliers: The Grubbs Test

4.6K
Sometimes, a data set can have a recorded numerical observation that greatly  deviates from the rest of the data. Assuming that the data is normally distributed, a statistical method called the Grubbs test can be used to determine whether the observation is truly an outlier.  To perform a two-tailed Grubbs test, first, calculate the absolute difference between the outlier and the mean. Then, calculate the ratio between this difference and the standard deviation of the sample. This...

Regression Toward the Mean01:52

Regression Toward the Mean

7.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Comparing the Survival Analysis of Two or More Groups01:20

Comparing the Survival Analysis of Two or More Groups

704
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

Stereotype Content Model02:16

Stereotype Content Model

15.7K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Mechanistic Models: Compartment Models in Individual and Population Analysis

321
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Area of Science:

  • Sociology
  • Demography
  • Public Policy

Background:

  • Research on migration status and its societal effects has grown significantly.
  • Limited representative data and variable imputation methods have hindered accurate analysis.
  • Existing methods for determining migration status often yield inconsistent estimates.

Purpose of the Study:

  • To introduce a novel, data-driven indicator for migration status.
  • To compare the accuracy of this new indicator against existing self-report and imputation methods.
  • To assess the impact of different migration status measures on poverty gradient analysis.

Main Methods:

  • Constructed a new migration status indicator by linking two federal surveys with the Social Security Administration's Numident file.
  • Utilized administrative records for a comprehensive dataset of U.S. citizens and legal residents.
  • Employed statistical models to predict poverty using the new indicator and compared results with self-reported and logic-based measures.

Main Results:

  • The new administrative indicator produced poverty estimates comparable to self-reported migration status in federal surveys.
  • Both administrative and survey-based measures showed divergent poverty gradients compared to logic-based imputation methods.
  • Evidence suggests potential bias in logic-based algorithms for imputing migration status.

Conclusions:

  • Administrative record linkages offer a promising approach for improving migration status research.
  • The developed indicator provides a more reliable measure for analyzing socioeconomic disparities related to migration.
  • Findings highlight the need for caution when using certain logic-based imputation methods for migration status.
