Understanding Data Analysis & Statistical Modelling
Raw data only creates academic and commercial value when transformed through rigorous, statistically validated analytical pipelines. VIGOORR provides end-to-end data analysis consulting for scholars, market researchers, corporate enterprises, and institutions. Whether handling complex survey datasets, longitudinal medical trials, high-frequency financial time-series, or qualitative interview transcripts, our data science and statistical consulting practice delivers mathematically sound analyses, assumption testing, effect size calculations, and publication-standard tables adhering strictly to APA 7th edition and peer-reviewed reporting standards.
Multivariate Statistical Analysis
Parametric and non-parametric testing, MANOVA, hierarchical regression, logistic regression, and factor analysis (EFA/CFA).
Structural Equation Modelling (SEM)
Covariance-based (CB-SEM via AMOS) and Partial Least Squares (PLS-SEM via SmartPLS) path modelling.
R, Python & SPSS Scripting
Reproducible data pipelines with documented clean code, reproducible notebooks (Jupyter/RMarkdown), and diagnostic test outputs.
Qualitative Analysis (NVivo)
Thematic analysis, inductive/deductive coding, sentiment classification, and inter-coder reliability (Cohen's Kappa).
Who Needs Data Analysis & Statistical Modelling?
Doctoral Researchers & Academics
Executing complex hypothesis testing, measurement model validation, and mediation/moderation analyses for dissertations.
Clinical & Health Science Teams
Biostatistical evaluation, Kaplan-Meier survival curves, odds ratios, and diagnostic test sensitivity/specificity.
Commercial Enterprises & Startups
Customer segmentation (cluster analysis), churn prediction, pricing sensitivity, and econometric forecasting.
Social Science & NGO Evaluators
Qualitative coding of focus groups and multi-site mixed-methods monitoring and evaluation (M&E) data.
When Should You Consider This Service?
You have collected raw primary survey or laboratory data and need to perform rigorous statistical analysis.
You need to test complex multi-variable mediation, moderation, or structural path models (SmartPLS / AMOS).
Your manuscript received statistical reviewer comments requesting robustness checks, bootstrapping, or endogeneity testing.
You have large qualitative text datasets (interviews, focus groups) requiring systematic thematic coding in NVivo.
What VIGOORR Delivers
Our consulting engagements produce structured, tangible outputs engineered to withstand institutional, academic, or legal scrutiny:
Data Cleaning & Pre-Processing
Missing value imputation (EM/Multiple Imputation), outlier detection (Mahalanobis distance), normality testing, and multicollinearity diagnostics (VIF).
Measurement Model Validation (EFA / CFA)
Exploratory and Confirmatory Factor Analysis evaluating construct reliability (Cronbach's Alpha, Composite Reliability) and validity (AVE, Fornell-Larcker, HTMT criterion).
Structural Path Modelling & Hypothesis Testing
Direct, indirect (mediation), and conditional (moderation) effect estimations with 5,000+ resample bootstrapping.
Econometric & Time Series Modelling
Stationarity testing (ADF/PP), Cointegration (Johansen), ARMA/ARIMA, GARCH volatility modelling, and panel regression (Fixed/Random Effects).
Publication-Ready Visualizations & APA Tables
High-resolution vector plots (ggplot2/seaborn), path coefficient diagrams, and formatted summary tables ready for journal insertion.
Our Consulting & Delivery Workflow
Every Data Analysis & Statistical Modelling project moves through a structured, transparent series of milestones:
1
Dataset Ingestion & Objective Review
Reviewing research hypotheses, conceptual framework, and raw dataset structure under NDA.
2
Data Screening & Assumption Testing
Testing assumptions of normality, homoscedasticity, linearity, common method bias (Harman's single-factor / Marker variable).
3
Model Execution & Robustness Testing
Running primary statistical models alongside non-parametric robustness checks and sensitivity tests.
4
Result Interpretation & Narrative Reporting
Drafting clear statistical interpretation explaining p-values, effect sizes (f², R²), confidence intervals, and hypothesis acceptance/rejection.
5
Client Walkthrough & Post-Delivery Support
One-on-one consultation explaining statistical rationale to prepare you for viva voce defenses or reviewer responses.
What You Need to Provide
To accelerate initial scoping and ensure precision, having the following information or documents ready is recommended:
Raw dataset in Excel, CSV, SPSS (.sav), or text format.
List of research questions, conceptual framework, and specific hypotheses.
Codebook or survey instrument showing scale mappings (Likert scales, categorical codings).
Preferred statistical software (R, Python, SPSS, SmartPLS, AMOS, Stata).
Frequently Asked Questions
Answers to common queries regarding our Data Analysis & Statistical Modelling consulting services:
Should I use CB-SEM (AMOS) or PLS-SEM (SmartPLS) for my research?
Covariance-Based SEM (CB-SEM via AMOS) is preferred for confirming established theories with normally distributed data and large samples. Partial Least Squares SEM (PLS-SEM via SmartPLS) is ideal for exploratory research, complex models with many constructs, mediation/moderation pathways, non-normal data, and smaller sample sizes.
Do you provide the underlying code and raw output files?
Yes. We deliver complete, well-commented R scripts, Python notebooks, or SPSS syntax files alongside raw log outputs so your analysis is 100% transparent and reproducible.
Can you help if our data does not support the initial hypotheses?
Yes. In academic research, non-significant findings are scientifically valid if analyzed with integrity. We provide post-hoc exploration, mediation/moderation insights, and robust discussions contextualizing why the data diverged from initial expectations.
