Product
A plain cake (pound cake) with four ingredients, like this one. Or the category Pound cakes.
Data
Four scenarios:
Nutrient | Product | Ciqual Cake | Median Cake |
---|---|---|---|
Fat | 24 | 25.6 | 23 |
Sat. Fat | 15 | 15.8 | 7.4 |
Carbohydrates | 48 | 46 | 49 |
Sugars | 29 | 26.8 | 28 |
Fiber | 2 | 1.1 | 1.2 |
Proteins | 6 | 5.94 | 5.8 |
Salt | 1.4 | 0.52 | 0.8 |
For easy reuse:
Product (24,15,48,29,2,6,1.4) Ciqual (25.6,15.8,46,26.8,1.1,5.94,0.52) Median (23,7.4,49,28,1.2,5.8,0.8)
The nutritional values for the Ciqual ingredients.
Nutrient | Flour | Sugar | Egg | Butter |
---|---|---|---|---|
Fat | 1.18 | 0 | 9.83 | 82.9 |
Sat. Fat | 0.17 | 0 | 2.64 | 55.4 |
Carbohydrates | 73.2 | 99.8 | 0.27 | 0.9 |
Sugars | 1.77 | 99.8 | 0.27 | 0.83 |
Fiber | 4.2 | 0 | 0 | 0 |

Salt | 0 | 0.0054 | 0.31 | 0.063 |
Flour: (1.18,0.17,73.2,1.77,4.2,9.95,0) Sugar: (0,0,99.8,99.8,0,0,0.0054) Eggs: (9.83,2.64,0.27,0.27,0,12.7,0.31) Butter: (82.9,55.4,0.90.83,0,0.7,0.063)
Least squares fit
R studio
The table below present fit results. This compares the product against the ciqual ingredients.
model | Flour | Sugar | Butter | Eggs | Intercept | sumR2 |
---|---|---|---|---|---|---|
lm | 0.265 | 0.274 | 0.249 | 0.182 | 0.994 | 0.30 |
lm forced intercept | 0.267 | 0.283 | 0.257 | 0.250 | - | 2.468 |
nnls | 0.267 | 0.283 | 0.257 | 0.250 | - | 2.486 |
Largest residual for salt. Can we add that in?
model | Flour | Sugar | Butter | Eggs | Salt | sumR2 |
