Interval Estimation for a Binomial Proportion
We revisit the problem of interval estimation of a binomial proportion. The erratic behavior of the coverage probability of the stan- d ardWaldconfid ence interval has previously been remarkedon in
A Temporal Analysis of Earnings Surprises: Profits Versus Losses
type="main" xml:lang="en"> I show that median earnings surprise has shifted rightward from small negative (miss analyst estimates by a small amount) to zero (meet analyst estimates exactly) to small
Corporate Governance and Firm Valuation
Gompers et al. [Gompers, P., Ishii, J., Metrick, A., 2003. Corporate governance and equity prices. Quarterly Journal of Economics 118, 107-155] created G-Index, a summary measure of corporate
Asymptotic equivalence of nonparametric regression and white noise
The principal result is that, under conditions, to any nonparametric regression problem there corresponds an asymptotically equivalent sequence of white noise with drift problems, and conversely.
A Temporal Analysis of Quarterly Earnings Thresholds: Propensities and Valuation Consequences
Applying a Burgstahler and Dichev (1997)/Degeorge et al. (1999) type methodology to quarterly data for the 1985–2002 time period, we show that, since the mid‐1990s, but not before then, managers seek
Valid post-selection inference
It is common practice in statistical data analysis to perform data-driven variable selection and derive statistical inference from the resulting model. Such inference enjoys none of the guarantees
In-season prediction of batting averages: A field test of empirical Bayes and Bayes methodologies
Batting average is one of the principle performance measures for an individual baseball player. It is natural to statistically model this as a binomial-variable proportion, with a given (observed)
