t Distribution and t Scores in R | R Tutorial 3.4 | MarinStatsLectures

In this video, you will learn how to calculate probabilities and find quantiles (or critical values) for the student t distribution in statistics using R. We will present the pt, dt and qt functions in R programming language.

This video is a tutorial for programming in R Statistical Software for beginners, using RStudio.

wow, it was awesome.. You made my work easy. Thanks a lot from Kerala, India.

Hi Mike, I'm really interesting about your videos!! It gives massive support to me.. I feel i need to know more about Probability and Statistics..For that could you please tell me the good sources which i can refer as a beginner .Thanks!!

[crgIN]

remember n-1 to get your degrees of freedom!! I was confused about why my t-score was off. it makes sense why r would not do that for you, but don't make my mistake!!

Hi Mike, Can i know why did you use -2.3(negative 2.3) when getting the two sided p-value without using +2.3(positive 2.3)[ at 2.24 min of the video] ?

[RiddaAli]

hi, Mike...
your videos are very helpful could you please share p-values of well known distributions...in detail

How can we get the data file to practise it?

Prof,
Thanks for this posting..self explanatory as usual.

You made my year, in 2015.

I have a problem. I have three datasets, namely, x, y, and z..respectively named longitudes, latitudes, and temperature in degree Centigrades...
I want to generate a 2D contour plot of parameter z, using r commands.

Kindly help me with the commands....for the contourplot of these datasets...

Longitudes..23456, 23578, 24567, 25678, 23211.



Temperature.. 12;34;54;23;21

Also, remember my earlier
I still await your r videos on Bayesian analysis, mcmc, winbugs, and kalman filtering.... All done in r or studio.

Happy New Year 2015

How to calculate when it is noncentral t distribution?

[antarhossain]

need r programming code for lattice structure, sir

How come that t-stat=2.3 became a q=2.3?

[JackIsNotInTheBox]

it's sad this is the only tutorial I can find for this. After this many years... smh
