Dr Danilo Petti



Danilo Petti undertook his undergraduate study in Economics at the University of Salerno to then continue with an MSc in Statistics and Actuarial Science (graduated in Sep. 2019, first of his court). In 2021 he graduated with an MSc in Statistics with Distinction at University College London to then complete a PhD in Statistics at the University of Salerno in 2023. During his doctoral years, he simultaneously followed and successfully completed the course in Advanced Statistics and Actuarial Science at the University of Florence. He is also a certified trainer (score 980/1000) of Statistical Analysis System (SAS). He is now interested in various research areas in statistical methodology and applications, including computational statistics, statistical learning methods, graphical models, causal inference, survival analysis and copula models.

Research and professional activities

Research interests

Copula link-based additive models for bivariate time-to-event outcomes

In medical research, the relationship and timing between two events, such as multi-organ diseases or maculopathy, are often of interest. However, it's not always possible to pinpoint exactly when these events occur due to missing information, a situation known as censoring. Censoring commonly occurs in case-control studies that extend over several years. Our objective was to develop a versatile tool capable of analyzing these event pairs despite the gaps in data. This tool had to be flexible enough to accommodate various types of missing information, for instance, when a patient discontinues their participation midway through a study, joins after the study has begun and leaves before its completion, or reaches the end of the study without the disease manifesting.

Key words: Copula

Variable Ranking in Bivariate Domain

In studies where we observe how long it takes for certain events to happen, it's essential to identify which factors are influential. However, this becomes increasingly difficult as the amount of data grows. Our goal was to develop a new method that can pinpoint these important factors effectively, even when dealing with a large amount of information and when some data might be missing or incomplete.

Key words: Survival Analysis

Analysis of Financial Time Series

The global financial ecosystem recently faced a significant challenge with the collapse of major institutions like Silicon Valley Bank, leading to widespread fear among investors. This event highlighted the potential for a systemic crisis, characterized by liquidity constraints and heightened market volatility. Amidst this turmoil, Bitcoin has emerged as a novel asset class, offering investors an alternative means of diversification. In response to these developments, our goal was to understand the impact of the banking crisis on Bitcoin and its potential as a stabilizing force in the face of global financial uncertainty. To achieve this, we set out to develop a banking index that could help isolate the effects of the banking crisis on Bitcoin and then analyze the resulting market volatility.
