Hello dear Rosane, I have just watched your videos, you teach incredibly, what if I want to plot values of three factors. I would facet one factor and two factors on the x-axis. how can i code this ?
I ended up with a different ANOVA table below. Can someone tell me where I made a mistake in my R code? Df Sum Sq Mean Sq F value Pr(>F) Glass 2 267 133 0.888 0.429 Temp_Factor 2 3141469 1570734 10450.918
Hi Rosane. Thank you for this. By the way could you explain how to do a Four way ANOVA? Examples are only available for 2 or 3 way anova only. It’s rarely explained how to perform 4 way anova or more factors. Would be really greatful to you.
Hello IOT. The four-factor experiments usually fall into a 2ˆk designs, where we test only two levels of each design factor. In this case, a complete replicate involves 16 runs, which is already a pretty large design. In this cases, it is also possible to run only a single-replicate of the design. There are several aspects and considerations involved on how to properly analyse large designs. I can do some videos on it, but for these more advanced analysis I strongly suggest you to take a full course to understand them. In the course "Design and Analysis of Experiments", I cover two-level four-factor designs, the idea behind single-replicates designs, designs in blocks (usually large designs are hard to run in homogeneous conditions), and fractionated designs.

thank you prof rosa. the content is very interesting and the presentation is masterful! good continuation
Glad you liked it!
Wow, amazing tutorial
Thank you!!!!
can someone help me cause i cant plot like in the video even i do the exact same thing. the code shows "error in plot... object 'Temp' not found"
Can anyone pls. tell me what is the name of this program and how can i download it?
