Tīmeklis2024. gada 15. nov. · Our lasso picked all 15 of the predictors we used to create our response variable – nice! It also picked 68 other predictors that weren’t in our model, but notice that the estimated coefficients for them (mean = 0) are much smaller than for the ‘true’ variables (mean = 0.89). This suggests that our lasso did a good job identifying … Tīmeklis2024. gada 23. jūl. · 对一篇影像组学的的论文（《Development and validation of an MRI-based radiomics nomogram for distinguishing Warthin’s tumour from pleomorphic adenomas of the parotid gland》）中方法进行复现。
