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 statistic can also be obtained using the summary of model in r. It also gives values of coefficient of determination or r squared and adjusted r squared.

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?

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.
