An integral equation for the identification of causal effects in nonlinear models
Wing Hung Wong
When the causal relationship between X and Y is specified by a structural equation, the causal effect of X on Y is the expected rate of change of Y with respect to changes in X, wh…
A calculus for causal inference with instrumental variables
Wing Hung Wong
Under a general structural equation framework for causal inference, we provide a definition of the causal effect of a variable X on another variable Y, and propose an approach to e…
Multivariate Density Estimation via Adaptive Partitioning (II): Posterior Concentration
Linxi Liu, Wing Hung Wong
In this paper, we study a class of non-parametric density estimators under Bayesian settings. The estimators are piecewise constant functions on binary partitions. We analyze the c…
Multivariate Density Estimation via Adaptive Partitioning (I): Sieve MLE
Linxi Liu, Wing Hung Wong
We study a non-parametric approach to multivariate density estimation. The estimators are piecewise constant density functions supported by binary partitions. The partition of the…
Optional Pólya tree and Bayesian inference
Wing H. Wong, Li Ma
We introduce an extension of the Pólya tree approach for constructing distributions on the space of probability measures. By using optional stopping and optional choice of splittin…
