Were you using DHS surveys as your data source?
Jessina McGregor
22:26
I assume this is simplified since it doesn't look like each quintile is represented?
Kalongo Hamusonde
26:46
Is it necessary to account for the multilevel structure of the data when building the models ?
Khai Tram
35:58
Lorenz curve?
Nikhet Chowdhury

Sorry did we start today’s lecture at 8:00am?
Nikhet Chowdhury
37:18

I am sorry, I will need to step away to restart my internet because my audio keeps cutting out
Jessina McGregor

Was each quintile modeled to have equal population sizes? if not, how did Q1 and Q5 compare?
Jessina McGregor
40:51
thx!
Khai Tram

Maybe you’ve thought about using cell phone mobility data to estimate contact/mixing among different groups..
Kylie Sage
46:37
Was there any public health action that came as a result of this model? i.e., was this model used to change policy or motivate vaccination campaigns?
Jessina McGregor
47:32
Is mixing referring to interaction between groups or changing states between groups?
Micaela Martinez - Emory University
48:01
Mixing is referring to the contacts among different groups
Khai Tram
48:02
There’s granular detail down to census tract
Allison Vestal-Laborde
48:20
You'd also have to assume that everyone had a phone.
Khai Tram
48:31
So there is some assumption but you can get down to pretty small geographic areas
Tara Prezioso
48:39
do you think that tracking people by their phone is ethical?
Tara Prezioso
48:46
without them knowing?
Gwenyth O'neill Lee
49:42
This was one of my questions earlier -how do you know that 'low SES' / 'high SES' is actually an important defining characteristic of how people group? I mean intuitively it makes sense, but people also group ethnically, geographically, by age, etc. It seems like you'd want some empirical evidence that people really cluster in their social interactions according to SES?
Tafadzwa
51:04
How did you define socio-economic status?
Gwenyth O'neill Lee
52:01
yes, thanks!
Khai Tram
52:37
It’s based on PCA of household assers
Tafadzwa
52:57
Okay thanks

Maia has her hand up
Gwenyth O'neill Lee

Measurement of SES is the kind of thing you can spend your whole research career on! I think people compare asset-based measures to other household economic indicators like purchasing power to validate. It's challenging to come up with cross-culturally valid SES measures I think.
Micaela Martinez - Emory University
58:39
I agree with Gwenyth, very difficult to make a measure that is valid across countries and contexts even within many countries
Tara Prezioso
01:01:15
yeah, that would be great... Thanks for asking that Nikhet
Nikhet Chowdhury
01:01:28
you're welcome!
