Cutting-Edge Expertise, Practical Results
My name is David Allsop. I am a consultant and professor with a PhD in Psychology and Neuroscience — which means the methods I bring to your work are the same ones used in cutting-edge research. But technical depth only matters if you can use the results. I specialize in translating complex findings into plain language, giving you the clarity to act.
Education and Credentials
Statistical Expertise
My statistical expertise includes the following models, among others:
- Structural Equation Modeling
- Multilevel Modeling
- Supervised Machine Learning Models
- Longitudinal Models (e.g., Latent Growth Models)
- Factor Models (e.g., Exploratory and Confirmatory Factor Analysis)
- Mixture Models (e.g., Latent Class Analysis, Growth Mixture Models)
I commonly combine several models for specialized analyses. Some examples are below:
Multilevel structural equation modeling using latent variables to account for measurement error with dyads (see my work), including with intensive longitudinal data (daily diaries; see my work)
Growth modeling with dyads (see my work; another work) and dyadic random intercept cross-lagged panel models (see my work)
Within- and between-group comparisons with dyads and latent variables (see my work), and group comparisons among dyads testing interventions (see my work)
Dyadic mediation models (see my work) and dyadic moderation models examining changes across time (see my work)
Latent profile analysis among dyads (see my work)
Method Expertise
I hold expertise across many methods, such as the following:
- Group Comparisons
- Predictive Modeling
- Psychometrics and Scale Development
- Power Analyses
- Research Design
- Survey Design
