 Jul2 awarded Curious May27 awarded Nice Answer Mar3 accepted Joint density with continuous and binary random variable Mar3 comment Joint density with continuous and binary random variable @ Michael Hardy. Thank you. I upwoted your answer originally, but someone downvoted it after that. Mar3 revised Joint density with continuous and binary random variable added 10 characters in body Mar3 asked Joint density with continuous and binary random variable Feb24 comment What are conditions on $x$ that make roots of $y^2 + 2xy - 2 = 0$ greater than 1 in absolute value? @ Git Gud Thank you! Does this mean that most likely I would not be able to find answer if $x,y\in\mathbb{C}\setminus\mathbb{R}$. Feb24 comment What are conditions on $x$ that make roots of $y^2 + 2xy - 2 = 0$ greater than 1 in absolute value? Yes, I corrected.

Ok, what about the other case? Feb24 asked What are conditions on $x$ that make roots of $y^2 + 2xy - 2 = 0$ greater than 1 in absolute value? Feb15 comment Bandwidth selection for kernel density estimation, using a Weibull kernel You might also check R and the package: cran.r-project.org/web/packages/np/index.html which has a lot of nonparameric functionality or the simple function density(x). Also your question would probalby fit more discussions on stats.stackexchange.com Feb15 comment Bandwidth selection for kernel density estimation, using a Weibull kernel My guess is that your noise is due to the innapropriately selected kernel. I would suggest using the Epanechnikov kernel and the "rule-of-thumb" bandwidth. It will estimate any sufficiently smooth density (including asymetric ones). Which software do you use? Feb15 comment Bandwidth selection for kernel density estimation, using a Weibull kernel May I ask what is the motivation of using the Weibull kernel?
