This paper deals with a formal identification of outliers in regression based on tests of hypotheses. The hypothesis is not the standard one but is based on performance criteria that relates to the coefficient
where the “latent” explanatory variableξ is not directly observed (hence the Greek letter); x2 is directly observed and measured without error; and the regression error ɛ behaves according to the usual assumptions—in particular, E(ɛi) = 0, and the errors are uncorrelated with each ...
This chapter discusses the use of instrumental variables for dealing with measurement error in regression covariates. Instruments are defined as observed variables that correlate with the mismeasured covariates, but do not correlate with the measurement
This irregular astigmatism cannot be optimally corrected using eyeglasses or soft contact lenses, additional correction measures are often required [1]. In this study we analysed the outcomes of TCAT for post-keratoplasty residual refractive error and astigmatism in patients who were intolerant to ...

In further investigations of bias, loss functions are evaluated to explain the MRP cost consequences of forecast errors. Estimating the loss functions of forecast errors through regression analysis demonstrates the superiority of loss functions as measures over typical forecast error measures in the MPS....
We fit a regression calibration model calculating bootstrap standard errors. In this model, we specify that qcalorie and satfat are replicate measures for an unknown covariate measure of the saturated fat intake of the individual. This model is fit in much less time than an equivalent SIMEX ...
measures, which only quantify correct responses. Indeed, by using this measure, we showed that the difficulties of patients in recognizing the speaker’s communicative intentions, i.e., lower sensitivity, are due to different reasons. In the case of irony, such lower sensitivity is mainly due ...
‘spherical probable error’. This is the three-dimensional analogue of the probable error of a single variate. Just as the probable error measures the half-width of the mean-centred interval which includes 50 per cent of the normal probability mass, the spherical probable error measures the ...
2.The article analyzed measure errors and causations which arised from different measure implements and means when the measures were on-line.针对CCD机器视觉系统,分析了用不同测量器件及方法进行在线测量时所产生的测量误差及其原因,并在此基础上对消除这些误差的方法进行了初步的探讨。 3.How to minish meas...
