R is one of the leading programming languages for data science. We know that data science requires strong leadership of statistics. R statistics are therefore critical for data science students. Statistics include a variety of issues that can be resolved manually. But R makes it much easier and faster to solve these statistical problems. Everything you need to get is good on R to solve most stats problems in no time.
R offers the best highly efficient statistical environment for statisticians. That's why it's known as The Language statistics R. R provides a variety of functions that help the data world perform statistics and probability functions, i.e. parametric distributions, summary statistics calculation, and many more. Here in this blog, we'll share all about statistics with R. But before we start with r. statistics let's take a look at the statistics packages.
Statistics for R
Qualitative Data
To analyze qualitative data, we use the RDQA package in R and is freely available to users. It is a free software application for qualitative analysis under a BSD license that works on almost every operating system, such as Windows, Linux, and Mac OSX. You can use it comfortably to analyze qualitative data. But keep in mind that it only contains coordinated pain text data.
Quantitative Data
Quantitative data are data sets that support calculations. Also known as continuous data. R offers a variety of tools and packages for quantitative data analysis. Quantitative data can be digital, as well as partial data set. It will automatically arrange the data according to requirements.
Probability Distributions
R makes probability distributions more comfortable than the standard policy. We can describe the probability function of different functions. Most often, we take density and distribution functions for probability. It is used to calculate theoretical quantities as well as sample notes. This will help if you don't have any external package in R to distribute the probability. This can be possible with built-in functions, such as dname, pname, qname, and rname.
Hypothesis Testing
Most of the time, researchers reject hypotheses. It is usually based on measurements of observed samples, the statistical mechanism known as hypothesotest testing. When the zero hypothesis is correct, the error of the first type rejects the hypothesis. Apart from that, when we need to delete the error portability of type I, we use the level of importance of testhypothesing, i.e. as described in the Greek letter α. R has broad support for testing hypotheses.
Simple Linear Regression
We use linear regression to predict the value of the Y-result variable based on one or more variables predicting X inputs. It helps us get a formula that the user can use to estimate the y response value when we only know the predictor values. For this, we use the lm function.
Conclusion
Now you may be quite confident that the statisticians prefer R over other languages for statistics. You can save plenty of time to solve the most complex statistics problems with R. Keep in mind that you can quickly start with R programming if you have a decent command over statistics and basic programming knowledge. If you want to get start learning data science, then you should clear the basics of statistics for R to start your journey of data science with R.
