Likelihood-based inference for clustered line transect data

The uncertainty in estimation of spatial animal density from line transect surveys depends on the degree of spatial clustering in the animal population. To quantify the clustering we model line transect data as independent thinnings of spatial shot-noise Cox processes. Likelihood-based inference is implemented using Markov chain Monte Carlo (MCMC) methods to obtain efficient estimates of spatia...

Inference for clustered data using the independence log-likelihood

Independence estimating equations (IEEs) are commonly used for the analysis of clustered data. Here, we use the properties of IEEs to adjust the “independence” log-likelihood function in the presence of clustering. The proposed adjustment relies on the robust sandwich estimator of the parameter covariance matrix, which is easy to calculate. We show that the adjusted log-likelihood competes favo...

Inference for Clustered Data

This article introduces clusteff, a new Stata command for checking the severity of cluster heterogeneity in cluster robust analyses. Cluster heterogeneity can cause a size distortion leading to underrejection of the null hypothesis. Carter, Schnepel, and Steigerwald (2015) develop the effective number of clusters to reflect a reduction in the degrees of freedom, thereby mirroring the distortion...

Hierarchical likelihood inference on clustered competing risks data.

The frailty model, an extension of the proportional hazards model, is often used to model clustered survival data. However, some extension of the ordinary frailty model is required when there exist competing risks within a cluster. Under competing risks, the underlying processes affecting the events of interest and competing events could be different but correlated. In this paper, the hierarchi...

Simulated likelihood methods for complex double-platform line transect surveys.

The conventional line transect approach of estimating effective search width from the perpendicular distance distribution is inappropriate in certain types of surveys, e.g., when an unknown fraction of the animals on the track line is detected, the animals can be observed only at discrete points in time, there are errors in positional measurements, and covariate heterogeneity exists in detectab...
