Generally it provides the core of complete web stacks and is designed to help build scalable web applications. When it comes to performance NGINX can easily handle a huge amount of traffic. The other main advantage of the NGINX is that allows you to do the same thing in different ways. For...
We can add descriptive statistics to our plot using thegeom_vline()function. This adds a vertical line geometry to the plot. First, we calculate a descriptive statistic, in this case, the mean price, using dplyr'ssummarize(). price_stats<-home_data|>summarize(mean_price=mean(price))price...
Now I will guide you to calculate the rate of return on the stock easily by the XIRR function in Excel. 1. Select the cell you will place the calculation result, and type the formula =XIRR(B2:B13,A2:A13), and press the Enter key. See screenshot: Note: In the formula =XIRR(B2:...
