Stein's method of moments

open access: yesScandinavian Journal of Statistics, EarlyView.
Abstract Stein operators allow one to characterize probability distributions via differential operators. Based on these characterizations, we develop a new method of point estimation for marginal parameters of strictly stationary and ergodic processes, which we call Stein's Method of Moments (SMOM). These SMOM estimators satisfy the desirable classical

Improved small‐sample inference for functions of parameters in the k$$ k $$‐sample multinomial problem

open access: yesScandinavian Journal of Statistics, EarlyView.
Abstract When the target parameter for inference is a real‐valued, continuous function of probabilities in the k$$ k $$‐sample multinomial problem, variance estimation may be challenging. In small samples or when the function is nondifferentiable at the true parameter, methods like the nonparametric bootstrap or delta method may perform poorly.

Finite models for positive combinatorial and exponential algebra

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract We use high girth, high chromatic number hypergraphs to show that there are finite models of the equational theory of the semiring of non‐negative integers whose equational theory has no finite axiomatisation, and show this also holds if factorial, fixed base exponentiation and operations for binomial coefficients are adjoined.

Growth problems in diagram categories

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract In the semisimple case, we derive (asymptotic) formulas for the growth rate of the number of summands in tensor powers of the generating object in diagram/interpolation categories.

The log Grothendieck ring of varieties

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract We define a Grothendieck ring of varieties for log schemes. It is generated by one additional class “P$P$” over the usual Grothendieck ring. We show the naïve definition of log Hodge numbers does not make sense for all log schemes. We offer an alternative that does.
