Help me understand this table: Unstandardized Logit Coefficient and Beta?

AI Thread Summary
The discussion centers on understanding the terms "Unstandardized Logit Coefficient" (ULC) and "Beta" in the context of logistic regression. A higher ULC indicates a stronger effect of an independent variable (IV) on the outcome, while Beta represents the same relationship but standardized for comparison across different IVs. The participants clarify that both metrics convey similar information, with larger values suggesting more favorable outcomes. Specific examples, such as "mudslinging" and "tone of the commercials," illustrate how these coefficients reflect their impact on voter turnout. Ultimately, the conversation emphasizes the importance of understanding what the coefficients are measuring to interpret the results accurately.

Hello, I am currently doing a project and trying to understand this table. I have a pretty good mathematical background but I know very little about statistics. Could someone explain, in simple terms, what this table is saying, specifically "Unstandardized Logit Coefficient" and "Beta"? Thanks so much!

Thanks. So, just so I'm clear, a higher unstandardized logit coefficient means what? And a higher beta means what?

I'm confused about the difference. It seems to me that both a higher unstandardized logit coefficient and a higher beta mean a higher turnout for a certain variable in the left-most column.
 
Can't tell what they are measuring from the chart alone.
eg.

IV: "mudslinging", ULC -0.07(0.03) ... would appear to be saying that mudslinging in the campaign has a slight negative effect on voter turnout but what are we to make of:

IV: "tone of the commercials" ULC 0.12(0.06) ... ?? I mean, what does "tone" measure and how was that measure turned into a logit coefficient?

You should look to see what they are "coefficients" to.

Whatver they are: the beta would be the same as the ULC only with their statistics standardized to unit varience. eg. they are showing the same thing in the sense that bigger numbers mean favorable ratios for the IV. The standardized measures are usually more useful for comparing different IVs to each other.

Thanks, that helps a lot. That's a good enough understanding for me right now, I'll look into what exactly those coefficients are. And yes, you are correct about what the chart is trying to say.
