Error in pt(abs(t_stat), df = summary(result_3)$df.residual, lower.tail = FALSE) : 数学函数中用了非数值参数

Translation: Error in pt(abs(t_stat), df = summary(result_3)$df.residual, lower.tail = FALSE) : Non-numeric argument used in mathematical function.

This error message indicates that a mathematical function was used with a non-numeric argument. In this specific case, the "pt" function was used with a non-numeric argument for the "df" parameter. This could be caused by a data type mismatch or an incorrect input value for the function.
