Row and Column Elimination Sampling Design +1 and its Efficiencies

Extended Abstract. It is a traditional way in biological, sociological, agricultural and geological studies to partition a geographical area into quadrats and then take a sample of them by a particular sampling design. We study the relevant characteristic of quadrats to estimate a parameter of the population. We suppose that the variable of interest has a positive spatial autocorrelation. Sampl...

Statistical Sampling Revisited

Auditing standards are undergoing revision in the wake of recent, massive audit failures. Legislative and regulatory bodies are focusing more critically on auditors than ever before. Yet, contemplated revisions to auditing standards leave untouched ambiguities and unresolved issues that have reduced the effectiveness of the authoritative literature for decades. One of the longest-standing issue...

Linear Thompson Sampling Revisited

We derive an alternative proof for the regret of Thompson sampling (TS) in the stochastic linear bandit setting. While we obtain a regret bound of order e O(d3/2 p T ) as in previous results, the proof sheds new light on the functioning of the TS. We leverage on the structure of the problem to show how the regret is related to the sensitivity (i.e., the gradient) of the objective function and h...
