Inequalities in Cancer Outcomes Network
Inequalities in Cancer Outcomes Network
Why are cancer outcomes poorer in some population groups in countries with universal access to healthcare? Why does access to optimal cancer care vary between different cancer patients? What are the mechanisms leading to such disparities? These are the type of questions our research aims to answer.

Some flexible parametric distributions for modelling time-to-event data
Time-to-event data appears in many research areas such as medicine, engineering, biology, and finance, to name but a few. For instance, modelling and understanding the survival times of cancer patients has become an important aim of many countries. In statistical terms, times-to-event correspond to a sample of positive observations, possibly censored due to lost of follow-up or administrative censoring. These observations represent either the time at which the event of interest happens (e.g. death of a patient or failure of an electric device) or the last time of follow-up. There exist several approaches to model time to event data, such as nonparametric, semiparametric, and parametric methods. Parametric distributions represent a parsimonious approach to modelling time-to-event data since they are typically easier to implement and to interpret. There is a large catalogue of flexible parametric distributions that can be used to model this kind of data. This shiny app illustrates different features (Hazard, Cumulative Hazard, and Survival functions) of interest of some of the most popular parametric distributions used to model time-to-event data. By changing the values of the parameters of the corresponding distributions, using the bars on the left hand side, the user can visualize the effect on the shapes of the hazard, cumulative hazard, and survival functions.

Based on a motivating example in non-communicable disease epidemiology, we generated a dataset with 1,000 observations to contextualize the effect of conditioning on a collider. Nearly 1 in 3 Americans suffer from high blood pressure and more than half do not have it under control [1]. Increased levels of systolic blood pressure over time are associated with increased cardio-vascular

Pattern of Comorbidities and Multimorbidity among Colorectal Cancer Patients in Spain
We found a consistent pattern of factors associated with a higher prevalence of comorbidities and multimorbidity at diagnosis among colorectal cancer patients at diagnosis in Spain. This pattern may add valuable insights for further etiological and preventive research and may help to identify patients at higher risk for poorer cancer outcomes and treatment.

Targeted Maximum Likelihood Estimation for a Binary Outcome: Tutorial and Guided Implementation
During the last 30 years, modern epidemiology has been able to identify significant limitations of classic epidemiologic methods when the focus is to explain the main effect of a risk factor on a disease or outcome.

Delta Method in Epidemiology: An Applied and Reproducible Tutorial.
Approximate statistical inference via determination of the asymptotic distribution of the statistics is a technique that epidemiologists and applied statisticians use routinely, we name it the classical delta-method, but there is a gap as it is not routinely taught and many applied researchers do not understand it neither its uses. The delta-method is a theorem which states that a smooth function of an asymptotically normal estimator is also asymptotically normally distributed. It can also be vi

The Comprehensive Guide to Conformal Statistical Inference
This interactive guide provides a visual and intuitive introduction to Conformal Inference, a modern framework for quantifying uncertainty in Machine Learning. Unlike traditional point predictions, which offer a single "best guess," Conformal Inference generates prediction intervals that come with a rigorous mathematical guarantee: the true value will fall within the predicted range at a user-defined confidence level (e.g., 95%). The core strength of this method lies in being model-agnostic and distribution-free. It doesn’t matter if you are using a simple linear regression or a complex deep neural network, and it doesn't assume that data follows a specific pattern (like a Normal distribution). The process typically involves: Splitting the data: Using a "calibration set" separate from the training data. Calculating Non-conformity Scores: Measuring how much a model’s prediction deviates from the actual values in the calibration set. Computing a Quantile: Finding an error threshold (q^) that covers the desired percentage of cases. The resource excels at breaking down these technical steps into digestible, interactive visualizations, making it accessible for practitioners who want to move beyond "black box" models and provide reliable, safety-critical predictions.
