What is the y axis in a density plot?
The y-axis in a density plot is the probability density function for the kernel density estimation. The difference is the probability density is the probability per unit on the x-axis. To convert to an actual probability, we need to find the area under the curve for a specific interval on the x-axis.
What does a density plot show?
A density plot is a representation of the distribution of a numeric variable. It uses a kernel density estimate to show the probability density function of the variable (see more). It is a smoothed version of the histogram and is used in the same concept.
How do you plot a density distribution in R?
To create a density plot in R you can plot the object created with the R density function, that will plot a density curve in a new R window. You can also overlay the density curve over an R histogram with the lines function. The result is the empirical density function.
What does the Y axis in a kernel density plot mean?
I missed your second question initially, but P ( x < 2) = 150 1000 = .15 means that the area under the curve to the left of 2 (i.e., the area of the two spikes at 0 and 1, more or less) is .15.

Which is the density function in a density plot?
The y-axis in a density plot is the probability density function for the kernel density estimation. However, we need to be careful to specify this is a probability density and not a probability. The difference is the probability density is the probability per unit on the x-axis.
How is a density plot similar to a histogram?
The y-axis is in terms of density, and the histogram is normalized by default so that it has the same y-scale as the density plot. Analogous to the binwidth of a histogram, a density plot has a parameter called the bandwidth that changes the individual kernels and significantly affects the final result of the plot.
How does per capita population change with density?
This process in which per capita population growth changes when population density changes is referred to as density dependence. The Ricker model is a classic population model which gives the expected number of individuals in a generation as a function of the number of individuals in the previous generation.
