我正在使用這個游戲 model：

m1 <- gam(mean_AD_scaled ~ s(Age, bs = 'ad', k = -1) +  Sex + ti(Age, by = Sex, bs ='fs'),  
          data = DF, 
          method = 'REML', 
          family = gaussian)

Output：

Family: gaussian 
Link function: identity 

Formula:
mean_AD_scaled ~ s(Age, bs = "ad", k = -1) + Sex + ti(Age, 
    by = Sex, bs = "fs")

Parametric coefficients:

但是當我使用 gtsummary 時，我得到了每個性別“交互”的重復值：

  tbl_regression(m1, tidy_fun = tidy_gam)

輸出

我在一份出版物中看到以下內容，我正試圖復制它的性別和年齡： 在此處輸入圖像描述

我不確定如何解決這個問題。 我的目標是為手稿打印一個表格，以便可以添加任何其他與 gam 相關的信息，如edf和R^2 。

我認為您在處理這些類型的交互時發現了一個錯誤。 在我們修復錯誤的同時，這段代碼應該可以滿足您的需求。 謝謝
