    • Correlation estimation using components of Japanese candlesticks 

      Popov, Valentin Mina (2016) - Journal article
      Using the wick's difference from the classical Japanese candlestick representation of daily open, high, low, close prices brings efficiency when estimating the correlation in a bivariate Brownian motion. An interpretation ...
    • Multiple regressions: the meaning of multiple regression and the non-problem of collinearity 

      Morrissey, Michael Blair; Ruxton, Graeme Douglas (2018) - Journal article
      Simple regression (regression analysis with a single explanatory variable), and multiple regression (regression models with multiple explanatory variables), typically correspond to very different biological questions. The ...
    • Stochastic complementarity 

      Manzini, Paola; Mariotti, Marco; Ülkü, Levant (University of St Andrews, 2016-09-30) - Working or discussion paper
      The Hicksian definition of complementarity and substitutability may not apply in contexts in which agents are not utility maximisers or where price or income variations, whether implicit or explicit, are not available. We ...
    • Underestimation of Pearson's product moment correlation statistic 

      Humphreys, Rosalind K.; Puth, Marie-Therese; Neuhäuser, Markus; Ruxton, Graeme Douglas (2019-01) - Journal article
      Pearson’s product moment correlation coefficient (more commonly Pearson’s r) tends to underestimate correlations that exist in the underlying population. This phenomenon is generally unappreciated in studies of ecology, ...
