🚨New paper at Stats in Medicine with @rahulalbussrk, @vadimZip, K. Merikangas! We introduce latent semiparametric Gaussian copula-based approach to unify functional principal component analyses of Non-Gaussian, Truncated, Discrete data from mHealth. https://t.co/j0jZReT8R9

We find intriguing weekly mood patterns: latent mood scores show a consistent happiness dip early in the week, rebounding on the weekend. In mood disorder subtypes, we found clear diurnal patterns: Bipolar I shows lowest happiness, followed by Bipolar II and MDD.

Excited to be invited by @USCArnoldSchool Epi and Biostat Department to present my work on #DigitalHealth tomorrow in the seminar at 1. @rahulalbussrk

[Debangan Dey @Debangan07]

Thrilled to share our new preprint on Graph-constrained Analysis for Multivariate Functional Data! Our method preserves intervariable graphs, backed by theoretical results. We unveil novel insights into pain fMRI research. 🧠📊 @datta_science @fMRIstats

Thanks @YoungStatS2 for the opportunity to showcase our work. Hope you find the demonstration useful.

Biased commentary 101 by @ItsObviousAndy

Rashford: Brilliant strike.
Saka: It’s De Gea’s fault. #ARSMUN

We prove the asymptotic normality of latent correlation matrix and regression parameter estimators and provide an efficient way to calculate the asymptotic variance in quadratic (vs quartic) time.

[Debangan Dey @Debangan07]

Technically, we use Semi-parametric Gaussian Copula to bridge observed Kendall's Tau pair-wise correlations to the latent correlations. This method is scale-free and robust.

[Debangan Dey @Debangan07]

We provide asymptotic-based inference and conventional intuition of linear models such as standardized and interpretable regression coefficients and goodness-of-fit via adjusted-R2.

Excited to share our (with @vadimZip) latest work on joint modeling of CTOB (continuous, truncated, ordinal, binary) mixed types variables. By mapping observed variables to latent space, we enable a unified regression modeling covering all CTOB mixed type outcomes.
