Multivariate data sets

Raw material propertiesMeasured characteristics of several batches (lots) of plastic pellets.3666700
Brittleness indexA plastic product is produced in three parallel reactors (TK104, TK105, or TK107). For each row in the dataset, we have the same batch of raw material that was split, and fed to the 3 reactors. These values are the …1538115
Room temperaturesTemperature measurements, in Kelvin, taken from 4 corners of a room.144411444
Six-point board thicknessThickness of 2x6 SPF boards from a saw mill.5000611286
Batch yield and purityThe two columns in the data set are: the percentage yield from a batch reactor, and; the purity of the feedstock. The feedstock is what we add to the reactor, and the yield is measured after the reaction is completed. …24126820
Bioreactor yieldsThe percentage yield from a bioreactor given the temperature, impeller speed, duration, and whether or not the reactor has baffles.1459443
Wood fibresA sample of aspen tree fibre as characterized by a fibre quality analyzer (FQA).2516563948
Tablet NIR spectral dataSpectra, measured in the transmittance mode, of 460 pharmaceutical tablets; readings are from 600 to 1898 nm in 2 nm increments.46065015084
Food textureTexture measurements of a pastry-type food.50523581
Cheddar cheeseConcentrations of acetic acid, H2S, and lactic acid in 30 samples of mature cheddar cheese. A subjective taste value is also provided.30414372
Oil company DOEExperimental data; testing amount of 4 materials added (A, B, C, D) in order to achieve a certain volumetric heat capacity, y.1956421
Distillation towerSnapshot measurements on 27 variables from a distillation column; measured over 2.5 years.2532712836
LDPEData from a low-density polyethylene production process. There are 14 process variables and 5 quality variables (last 5 columns).54195698
Raw material outcomeSix characterizing measurements for batches of plastic pellets; the outcome when using this material, either Poor or Adequate, is also provided.2476627
Wine DOEData from a fractional factorial for profiling a new wine. The last 5 columns are the taste values from a panel of judges. Higher values are a better overall taste.16134588
Class gradesGrades from a Chemical Engineering course at McMaster University.99612748
Food consumptionThe relative consumption of certain food items in European and Scandinavian countries. The numbers represent the percentage of the population consuming that food type.162021794
Silicon wafer thicknessThickness of a single wafer, measured at 9 locations for 184 consecutive batches. A single wafer is removed from a tray of wafers (always at the same position for each batch of wafers) after the chemical vapour decomposition process is …18494697
SolventsPhysical properties of various chemical solvents, such as melting point, boiling point, dipole moment, refractive index, density, solubility.10394811
Film thicknessThe thickness of a plastic film is measured in 4 positions after being cut. The position of the measurements are top right, top left, bottom right and bottom left.16043681
PeasThe taste of 27 pea varieties as measured by judges. After blanching the peas, the peas were quick-frozen, packed into bags and stored for 3 months.60175015
Kamyr digesterPulp quality is measured by the lignin content remaining in the pulp: the Kappa number. This data set is used to understand which variables in the process influence the Kappa number, and if it can be predicted accurately enough for …301228878
SawdustSawdust from birch, pine a spruce were blended in specific ratios. The corresponding NIR spectra are recorded.5412042792
Travel timesA driver uses an app to track GPS coordinates as he drives to work and back each day. The app collects the location and elevation data. Data for about 200 trips are summarized in this data set.2051320148
Flotation cellData from a zinc-lead flotation cell measured on 5 variables; recorded from the PLCs.292257432
Blender efficiencyThe effect of 4 factors on blending efficiency.1855460
Certificates of analysisFour properties of an important powder raw material were transcribed from the supplier's certificates of analysis.12253461
Systematic methodData are from an open-ended question on a final exam. The values are the grades achieved for the answer to that question, broken down by whether the student used a systematic method, or not. No grades were given for using …4423610
Industrial Batch Polymerization55 batches, each aligned to 100 equal time intervals (K = 100) for J=10 process variables measured throughout each batch. The batches are stacked vertically (rows 1-100 = batch 1, rows 101-200 = batch 2, etc). Values are scaled/normalized (dimensionless, …1794
Industrial Batch DryerA single workbook holding all four blocks, one per sheet: Z_operations: Operating-condition initial values; Z_chemistry: Chemistry initial conditions; X_batch: Aligned in-batch trajectory data; Y_quality: Final quality attributes (CQAs); The 59 batches in X_batch are stacked vertically with 325 samples each …1782
Sensory panelTwo synthetic, fully generic files used as a tutorial by the "descriptive panel data" tutorial in the process-improve package. Ten assessors scored eighteen products on nine sensory attributes; a companion table gives measured product covariates. The dataset is synthetic to …138
