I know the rule, ratios greater than 1.96 (in absolute value) suggests that the coefficient is statistically significantly different from 0 at the 95% confidence level. A threshold of 1.645 is used for 90% and so on.

But in my case I have also t-ratio values ranging from 15.xxx to 23.xxx

How do I interprete them? Does this mean they are highly significant?

And is this at the 99% level?

Thanks
