Thus, the realization of the new shrinkage procedure is the following: 1.) perform the discrete wavelet transform, 2.) fit the local polynomial regression curve on the coefficients with the wi weights; 3.) get the residuals; 4.) get the median absolute value of the residuals; 5.) ...

Trend line is fit with linear regression. Shaded area corresponds to 95% confidence interval of the mean performance given the number of samples in a cancer study (n = 24). d MethNet association effect as a function of distance. Associations are grouped based on their ranked distance to...
The workhorse of applied research is linear regression. To draw inferences based on the regression models you fit, you need to ensure that the methods for estimating standard errors or otherwise calculating confidence intervals and p-values are robust to violations of the i.i.d. assumption. For...
The response variable is the total age-adjusted mortality rate per 100,000, which is a linear combination of 15 covariates. For a more detailed description of the data, refer to38,39. First, we employed the least squares method to fit model (1.1) and obtained the residuals. The diagnostic...
