Geographically weighted regression presentation
Просмотров 6223 года назад
This video discusses principles and trouble spots for presenting the results of GWR. With this technique, it’s especially important to ensure you explain fully what the results mean.
Geographically weighted regression limitations
Просмотров 5833 года назад
This video presents limitations to GWR. They stem from the small sample size, local multicollinearity, and the problems of having multiple statistical tests that aren’t fully independent of each other.
Geographically weighted regression interpretation
Просмотров 1,7 тыс.3 года назад
This video presents ways to interpret GWR, making sure that while each observation gets its own results, they relate to the entire neighborhood around that observation.
Geographically weighted regression introduction
Просмотров 4,1 тыс.3 года назад
This video introduces the third means of accounting for space in regression-geographically weighted regression (GWR). It is used when the coefficients are themselves not constant from place to place.
Multivariate regression presentation
Просмотров 633 года назад
This video discusses strategies and trouble spots for presenting the results of multivariate regression. What is in the table is discussed as well as issues about presenting conclusions about the coefficients.
Multivariate regression interpretation
Просмотров 1263 года назад
This video presents issues about interpretation of multivariate regression. The main concepts are that the coefficients are now marginal coefficients, and we now use an adjusted R-squared value.
Multivariate regression introduction
Просмотров 873 года назад
This video introduces the concepts extending bivariate regression to multivariate regression. The main addition is having more than one independent variable within the regression model.
Spatial regression: presentation
Просмотров 3743 года назад
This video presents strategies for interpreting and presenting spatial regression, including what is included in the table for the results.
Spatial lag and error regression
Просмотров 1,7 тыс.3 года назад
This video presents two forms of spatial regression and the difference between them. Spatial error regression uses the average residuals of the neighbors to influence the prediction at a location, while spatial lag regression uses the average of the neighbors’ dependent variable values to influence the prediction.
Spatial regression: autocorrelation of residuals
Просмотров 4683 года назад
This video presents more information about the part of the spatial regression process with the autocorrelation of the residuals: the choice of spatial weights matrix; and positive versus negative autocorrelation.
Spatial regression overview
Просмотров 2,2 тыс.3 года назад
This video presents an overview of spatial regression concepts. The process that typically involves spatial regression starts with linear regression, then we analyze the spatial autocorrelation of the residuals. If they are autocorrelation, we choose the type of spatial regression based upon what we suspect is causing that autocorrelation.
Correlation and regression
Просмотров 913 года назад
This video presents an introduction to concepts of correlation and regression. Correlation is the relationship between two variables and regression adds to that to enable making predictions of the value of one variable from the values of the other.
Regression presentation
Просмотров 493 года назад
This video presents the conventions for writing about results of regression analysis, including what to put in a table and what interpretations to give.
Regression pitfalls
Просмотров 1253 года назад
This video presents some pitfalls with analyzing and interpreting regression results. Some are based upon assumptions the regression method makes of the data, and a couple others are frequent errors people make.

    Excellent overview. Thank you. A more likely (less politically charged) scenario for the relationship not being geographically consistent would be that, in places where there are more people living in the same household wearing a mask is less effective in preventing disease because you have more chances of getting infected. In fact, this was observed during the COVID-19 pandemic in urban areas. Reference: www.ncbi.nlm.nih.gov/pmc/articles/PMC8328572/

    Great video. Thanks! Lagrange Multiplier test helps decide between spatial lag and spatial error model, if the project background is unclear on whether there are missing factors or whether there’s geographical dependence.

    I hope your students appreciate your clear and concise explanations and expectations. And that you are using data related to a contemporary, real-life problem. While they might not suspect it, I bet this lecture was motivated by your reflections on how students in past years have botched this assignment. Thanks for making this available! Also, that is a very large sheet of butcher's paper.

      Thanks for the comment! (I hadn't been checking the channel since the semester ended, so that's why the response is so delayed.) Part of the course is about communication through the WVU "SpeakWrite" system, which is why there's this emphasis on presentation. Also, that's actually a large DIY whiteboard from Lowe's.

  • @mariag3456

    Thanks for nice explanation :) But I have a question I really need an answer to, so please if anyone could help... 1. I fitted multiple spatial regression models - spatial lag model, spatial error model and spatial durbin model and more. My question is, how do I check the assumptions of normality and homoscedasticity of errors? In classical linear regression, the diagnostics is done on standardized or studentized residuals, but how do I standardize residuals in these spatial models? When I use raw residuals from the spatial models and do QQplot, they always have this "S" shape. Does it mean the models are wrong? 2. The same for weighted version of spatial error model. Which residuals should I use to check the model assumptions?
