Web1 day ago · Q: I would like to use R to generate a histogram which has bars of variable bin width with each bar having an equal number of counts. For example, if the bin limits are the quartiles, each bar would represent 1/4 of the total probability in the distribution. WebMar 9, 2024 · Probability Density Functions (PDFs) Recall that continuous random variables have uncountably many possible values (think of intervals of real …
