Simple Linear Regression in R Programming | Fitting Linear Model in R
This video is about simple linear regression in R. The simple linear regression model is used to predict the outcome of response variable or dependent variable on the basis of one explanatory variable or independent variable. lm () function is used to fit a linear model in R. The model can be saved with any object name. The values for intercept or alpha and beta or regression coefficient can be obtained by printing out the model.
The summary function can be used to get the summary of a linear regression model. With summary function, you can get values of minimum, maximum, first quantile of residuals. Similiary, standard errors of intercept and regression coefficient, p values and t statis...

Some of information is wrong.. please update information and concepts.
Can you highlight any wrong information? Thanks!
@@AnimalSciences 1. range of repeatability is 0 to 1. 2. Information on Grouping of repeatability as low, medium & high should be given
@@hardik.sharma1 Repeatability is the correlation between repeated records of a trait in a population and it can range from -1 to 1. However, it's very rare that you get negative value for Repeatability but still it's possible to get negative value of Repeatability. For better understanding of this topic I would recommend you to go through the Repeatability topic in 'Understanding Animal Breeding Book by Richard M. Bourdon'.

what is R used for?
R is a programming language (software), that is used for statistical analysis and data visualization.
@@AnimalSciences Thank you for the reply Could R be used for Lotteries and or pattern recognition within lotteries?
@@1realtruthrightnow742 it can be... But you should be expert in statistics.

The formula for estimation of broad sense heritability was H²=vG/vG why don't we use that instead of H²=2(r MZ. - r DZ) I don't get it
Heritability is the proportion of phenotypic variance that is due to genotypic variance. Mathematically, it can be expressed as vG/vP. So, this is how it is expressed but to actually calculate it you need to have calculated phenotypic and genetic variance first. To calculate phenotypic and genetic variance scientists have developed different methods which are explained in this video. It is also explained in this video why it is very difficult to calculate broad sense heritability. All of these methods are based on ways to calculate similarities or differences in living organisms. For example, correlation tells us the strength of relationship between two variables. So, correlation can be used to calculate heritability. I hope you got the point. If you want to fully understand these concepts then you can watch the videos series on heritability and methods to estimate heritability.

Do you have sources? So that I can go deeper?
You can get more details on this topic from the book Understanding Animal Breeding by Richard M. Bourdon

Thank you sir for sharing it . Plz send the link of genetics of livestock development JF Lasley if it access.
I think it's not freely available. You can purchase it from Amazon.
My brother thank you very much. I like your lecture . I have one question for you. Are these two options that are only available to enter data in to R or other more ? please show us all the options.
There are different ways to load data in R. If you have data in a CSV file then you can use these methods. If your data is in txt format then you can use the method explained in the following video: ruclips.net/video/58fR3gV6pcY/видео.html

In the case, that one dam gives more than one offspring, would the weight be the average?
Yes, it will be fine to take the average of all the offspring of a single dam.
Too narrow a definition of domestication for me. I include all living things that can be cared for and exploited. The full spectrum is from laboratory microorganisms to human slaves/employees.
Yes, you are right
