5. CATTLE SELLING DECISIONS
Households in which women own cattle and women make
the cattle selling decisions are more likely to sell cattle and are
more likely to have higher incomes overall.
PERMISSIONS TO ATTEND MEETINGS
Whether or not women producers need permission to attend meetings, both
within and outside of their village is influenced by whether or not they own
cattle, the economic status of their group and time.
Women who own cattle need less permission to attend meetings.

SDVC has collected and analyzed over 350 variables encompassing 863 groups, 45 field facilitators and 2 regions spanning 4
years.
The data has been collected at the household level, the static group level, and the dynamic group level (which changes over
time) over eight waves from 2009-2012.
Given this, advanced statistical methods are required to produce accurate results.

Generalized Linear Mixed-Effects models
Summary of Statistical Models Used
To accurately analyze the evidence on how SDVC interventions are working, we built statistical models that looked at all the levels simul-
taneously and controlled for the context in which the household exists (in this case, we included various group and program level vari-
ables).
Most of the trends and effects presented in the findings have controlled for many confounding and mediating variables in addition to the
primary variables of interest, including:
Geographic variables (upazila, region)
Group effect (group number, group contextual variables)
Household differences (family size, number of cows, breed of cows).
We used the R software for statistical computing. R is a free software environment that is widely used by statisticians. R is powerful and
uses the most up to date algorithms available due to its open source nature. The R packages contain functions for working with the com-
plex type of data that is involved in this project. These functions are not established in most other statistical packages.
We primarily used R to build mixed-effects regression models with both fixed and random effects. This we essential for accuracy as this
data has both nested effects (such as households within groups within regions) and crossed effects (such as groups within phases within
PPT rounds).
Due to the complex nature of the data, all of the models in this analysis were done using generalized linear mixed-effect models. Each of
the models in this presentation control for the size of the household cattle herd, the phase of the learning group of the household, the ef-
fects of time on the outcomes, and the contextual difference between the household’s results and the group’s results (ie. the within-house-
hold trend and the between-household trend.)
Generalized linear mixed-effect models (GLMMs) are a class of models designed for the analysis of clustered and longitudinal data with
non-normal dependent variables. In our models we have used a binomial link funtion and a penalized quasi-likelihood methods. All our
models include both a random intercept and a random slope. Each model includes fixed effects such as size of herd, time of collection
and phase of group. Each model also includes a series of random effects including the learning group and time. This method properly
controls for the fact that each group is meaured repeatedly as well as the fact that the data is clustered in several dimensions (ie. phase and
geography)
The acceptable significance level for all of our models is alpha = 0.05.
