This paper proposes to estimate the educational production functions of Senegal from PASEC 2014 data at primary level beginning and end schooling by BOX-COX (1964) transformation. We do not impose a linear functional form priori but propose determine it using model. The results obtained indicate that widespread use is appropriate, least with respect Senegalese data. On other hand, this transfor...

Time series forecasting methods are used by an evolving field of data analytics for the prediction market trends, sales, and demands. Turkey is major producer hazelnut in world. If wants to continue its domination protect price-setting role, time could be key factors accordingly. There a few studies that focused on export quantities Turkey, this study uses recently developed algorithm implement...

The data-driven Haar-Fisz (DDHF) transformation was recently developed to stabilise the variance of data with an increasing (but otherwise unknown) mean-variance relationship. This report investigates the empirical bias of the DDHF transform and compares it to the much used Box-Cox transformation, using both simulated Poisson counts and data of the deaths of coalition personnel in Iraq.

We investigate the effect of power transformation of raw scores on the responsiveness of quality of life survey. The procedure maximizes the paired t-test value on the power transformed data to obtain an optimal power range. The parallel between the Box-Cox transformation is also investigated for the quality of life data.

BackgroundWhile dealing with skewed outcome, researchers often use log-transformation to convert the data into normal and apply commonly used statistical tests like t-test, linear regression, etc. However, log-transformed will not be at all times. In such situations, Box-Cox transformation (BCT) can transform normal. problem arises when researcher wanted predict outcome in original scale. There...

Epidemiological and experimental data support the use of nonsteroidal anti-inflammatory drugs, including specific inhibitors of cyclooxygenase 2 (Cox-2), as chemopreventive agents in a number of epithelial cancers, including colon, mammary, esophageal, lung, and oral cavity (1). There is also evidence to suggest that nonsteroidal anti-inflammatory drugs may be chemopreventive against ovarian ca...
