Hi,

Given the values, I was not able to understand the phrase

"The variables sex, age and ph.ecog have highly statistically significant coefficients, while the coefficient for ph.karno is not significant." Why would "ph.karno", which has a p-val of 0.005 be insignificant?

Could you please elaborate more on this?

Thanks

E

age: 0.042
sex: 0.0015
ph.karno: 0.005
ph.ecog: 2.7e-05
wt.loss: 0.83

Oh sorry, this is a mistake.

The correct phrase is "the variables sex, age and ph.ecog have highly statistically significant coefficients, while the coefficient for wt.loss is not significant."

I will update the article accordingly.

Thank you for pointing this out.

How about "ph.karno"? (p-value: 0.005)
