Learning to Estimate Stochastic Diffusion Processes

Summary

The document raises a learning challenge in econometrics: understanding maximum-likelihood estimation of transition densities and stochastic diffusion processes. The author has experience with stochastic calculus and fundamental econometrics but finds the mathematical texts and papers difficult without a background in real or complex analysis. The central takeaway is that conceptual explanations and accessible reading material can help bridge the gap between intuitive understanding and formal derivations.

No estimator, worked example, empirical result, or specific reading recommendation is provided. The document is a request for advice rather than a tutorial, so it offers little guidance on how to implement or evaluate a diffusion model. Its relevance is mainly as a pointer to the mathematical prerequisites that can make likelihood-based diffusion estimation challenging for applied researchers.

Key ideas

• Maximum-likelihood estimation of transition densities is a topic in stochastic diffusion modeling.
• A background in stochastic calculus and econometrics may not make mathematical texts easy to follow.
• The document identifies real and complex analysis as gaps that can hinder a reader's progress.
• It asks for accessible resources but does not provide any specific recommendations.

So, in an advanced Econometrics course, the current topic relates to estimating transition densities and diffusion processes by MLE, such as this R package doc describes, for ex., and I have to admit to myself that I am starting to get lost.

What book(s) would you recommend for someone that has no background in Real/Complex analysis, yet still possesses a decent understanding of stochastic calc. and good background in fundamental econometrics? I am asking this because I feel most of the concepts are intuitive (if still the tiniest bit complex) once someone finally explains them to me, but actually following math texts/papers is difficult without a pure math background.

Any other quants that have experienced this can give me reading advice?
