[R] interpret a p-value result as a significance of a linear regression in terms of sigmas

so, as extension, for a multivariate linear regression for which the p-value associated to F statistics is not the same as the p-value for each variable of the regression. Thanks in advance, Best Regards Jean-Philippe Fontaine -- Jean-Philippe Fontaine PhD Student in Astroparticle Physics

Re: [R] R basic

Hi, Since you didn't provide us any detail of what you tried to do so far, I can point you out to the dplyr library. It will make your life easier while dealing with dataframes (well at least it makes mine easier). Cheers Jean-Philippe On 09/11/2017 16:05, Hye Joon Yoon wrote: Can a

as I wanted (so as a scalar), I don't see any difference in the result when I call this function draw.circle2, the stripes are not drawn inside the circle. I don't know if it is normal. Thanks, best Jean-Philippe On 14/06/2017 19:29, David Winsemius wrote: On Jun 14, 2017, at
