    silhouettes of skinny people. The first step it tells you to do is to put a finger on the “E” key for items that belong to the thin people category, and to put a right hand finger on the “I” key for those that belong to the fat people category. Making an error will cause a red X to appear on the screen. in the directions you are instructed to go as fast as you can while being accurate. In the second round of the test the categories change, the “E” key is now for bad words and the “I” key is now for good

  • Abstract Survival Analysis

    1170 Words  | 5 Pages

    Abstract Survival analysis is normally used to describe the analysis of data that depend on the time between constant starting point until the occurrence of specific event or endpoint. There are certain aspects of the survival analysis data, such as censoring and non-normality, which can generate great difficulty when trying to analyze data using traditional statistical models. In this paper, the Kaplan-Meier estimator is used to estimate the survival function. Also Log-Rank test is used to compare

  • Hastings Point Lab Report

    Introduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and

  • Summary: Socioeconomic Inequality In Health

    1695 Words  | 7 Pages

    The next natural step after determining the socioeconomic inequalities in a health variable is to disentangle the sources of the socioeconomic inequalities. The method for decomposing the inequalities into their contributing factors proposed by Wagstaff et al (2003) has become a staple in empirical research on socioeconomic inequalities in health. Wagstaff et al (2003) have demonstrated that if the relevant health outcome, h, can be expressed as a linear function of a set of k covariates, as follows:
