Hi there, I have two series of data. plotting the density function of both gives me an idea about the difference of the data. But I would like to quantify the difference I see.
a <- rnorm(100) b <- rnorm(100) da <- density(a) db <- density(b) The problem is that da$x and db$x are different and so I have difficulties to compare them... Is there any way to force the density funtion to produce the values for the same x-steps? Or is there any other statistical approach I should use for comparing two density functions? I need to quantify how much the data-series differ (density function is rather complex in my case with skew and several maximas, so not easily to describe as a mathematical function. Sorry, I'm not that deep into statistics. Any comments / keywords on this is welcome...
