Rstudio is a tool do do statistical analysis on data.
Recipe
The tool can be used to find the recipe of products.
Steps
We use the order as found on packaging, i.e. fat, sat. fat, carbs, sugar, fiber, proteins, salt).
Create the product data, e.g:
product <- c(58.0, 6.4, 6.4, 4.2, 8.5, 0.01)
Create the individual ingredients, eg.:
walnuts <- c(67.3, 6.45, 6.88, 3, 6.7, 13.3, 0.1)
Create the ingredients, e.g.:
ingredients <- c(walnuts, hazelnuts, cashews, almonds)
Create the array for 4 ingredients, e.g.:
Z <-array(ingredients, dim=c(7,4))
Fit:
lsFit <- lm(y~Z)
Fit with no intercept:
lsFitZero <- lm(y~Z +0)
