In importbq/bis557: Package for BIS557

Bis557

This Package contains my homeworks for Bis 557

Installation

The development version of the packages

install.packages("bis557")

And the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("importbq/bis557")

Example

We have an example here to show the usage of linear_model:

library(bis557)
#> Loading required package: rlang
#> Warning: package 'rlang' was built under R version 3.6.2
#> Loading required package: dplyr
#> Warning: package 'dplyr' was built under R version 3.6.2
#> 
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':
#> 
#>     filter, lag
#> The following objects are masked from 'package:base':
#> 
#>     intersect, setdiff, setequal, union
#> Loading required package: foreach
#> Loading required package: rsample
#> Warning: package 'rsample' was built under R version 3.6.2
data(iris)
fit_linear_model <- linear_model(Sepal.Length ~ ., iris)
print(fit_linear_model)
#> $coefficients
#>       (Intercept)       Sepal.Width      Petal.Length       Petal.Width 
#>         2.1712663         0.4958889         0.8292439        -0.3151552 
#> Speciesversicolor  Speciesvirginica 
#>        -0.7235620        -1.0234978 
#> 
#> attr(,"class")
#> [1] "my_lm"

We see that gradient descent achieved very good results for OLS.

Please read Vignette for details

HW2 Vignette has the solution to HW2

HW3 Pdf has been included in the Vignette folder

HW4 Pdf has been included in the Vignette folder. Benchmark(test code) is produced in chunck.
