Non-communicable diseases #NCDs cause between 30-40% of deaths in Kenya and over 50% of total hospital submissions in East Africa, with Cardiometabolic diseases #CMDs driving much of this burden. A new partnership between @novonordiskfond @MOH_Kenya, @SciforAfrica and @NCDAllianceKe is addressing this challenge by closing the research-to-implementation gap for #NCDs & #CMDs.

A great intro to mixed methods research by Harvard Catalyst:

[Joachim Schork @JoachimSchork]

Multicollinearity is a common issue in regression analysis where predictor variables are highly correlated, leading to unreliable estimates of regression coefficients.

Understanding and addressing multicollinearity is crucial for accurate and reliable statistical modeling.

Challenges of Ignoring Multicollinearity:
❌ Unreliable Coefficient Estimates: Ignoring multicollinearity can result in inflated standard errors and unreliable estimates, making it difficult to determine the true effect of each predictor.
❌ Misleading Interpretations: High multicollinearity can lead to misinterpretations of the significance of predictors, potentially leading to incorrect conclusions.

Benefits of Addressing Multicollinearity:
✔️ Improved Model Accuracy: Properly handling multicollinearity ensures that the estimated coefficients reflect the true relationship between predictors and the outcome variable.
✔️ Enhanced Predictive Power: Addressing multicollinearity helps in building models that generalize well to new data, improving prediction quality.

To handle multicollinearity effectively, consider the following approaches in practice:
🔹 R: Use the car package and the vif() function to detect multicollinearity. If necessary, apply principal component analysis (PCA) or remove highly correlated variables.
🔹 Python: Utilize the statsmodels library to check Variance Inflation Factor (VIF) values and consider using dimensionality reduction techniques like PCA from the sklearn library.

In the accompanying visualization, based on an image from Wikipedia (link: https://t.co/lWcDlwEJN2), the true parameters are reliably estimated when predictors are uncorrelated (black case), but estimation becomes unreliable when predictors are correlated (red case).

To explain this topic in further detail, I collaborated with Micha Gengenbach to create a comprehensive tutorial: https://t.co/9B6Aaxj9jT

As 2024 comes to a close, ASLM reflects on a year of progress in strengthening laboratory systems, enhancing health security, and driving research and innovation across Africa. Through expanded diagnostic networks, workforce training, policy advocacy, and global partnerships, we have made significant strides in improving access to quality healthcare.
We extend our heartfelt thanks to our partners, donors, and teams for their unwavering support, and we look forward to building on this momentum in 2025.

On this International Day of #EpidemicPreparedness, we highlight the critical role of women in shaping resilient health systems.

Women are 70% of the health workforce but <25% of leaders. Amplifying their voices is key to epidemic preparedness & equity.
