Experiential Learning, Narrative‐Based Learning, and Insurance Adoption: Experimental Evidence from Kenya

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract We compare the impact of two extension modalities on knowledge accumulation and willingness to pay for a weather index insurance product among smallholder farmers in Kenya. One approach to extension is based on experiential learning and involves participation in an incentivized framed experiment (or game).

How data or error covariance can change and still retain BLUEs as well as their covariance or the sum of squares of errors

open access: yesAustralian &New Zealand Journal of Statistics, EarlyView.
Summary Misspecification of the error covariance in linear models usually leads to incorrect inference and conclusions. We consider two linear models, A$$ \mathcal{A} $$ and B$$ \mathcal{B} $$, with the same design matrix but different error covariance matrices. The conditions under which every representation of the best linear unbiased estimator (BLUE)

ABSTRACT Ants have been proposed as good models to study ageing and the effects of extrinsic mortality because of their long lifespans and plasticity of ageing within species. We discuss how age‐dependent extrinsic mortality might influence queen lifespan, and how the effect of age‐independent extrinsic mortality needs further study, accounting for ...

A Cost of Misclassification Adjustment Approach for Estimating Optimal Cut-Off Point for Classification

open access: yesJournal of Probability and Statistics
Classification is one of the main areas of machine learning, where the target variable is usually categorical with at least two levels. This study focuses on deducing an optimal cut-off point for continuous outcomes (e.g., predicted probabilities ...
