Les fonctions les plus utiles sont écrites dans une police plus grande.

catego

Determining groups based on the results of a pairwise function

check_ech - Determine the differences in mean that I can detect for a known sample size

cor_ech

Anticipate the sample size that will be needed to detect a correlation (if there is one)

m.test - fonction très utile de comparaison de moyennes, rangs ou médianes pour 2 à n catégories. Choisit et réalise automatiquement tous les tests nécessaires (contrôle de la normalité, des variances) avec bootstrap et en s'adaptant aux données (appariées, ordinales...).

int.ech - fonction pour calculer l'intervalle de confiance d'un échantillon.

identify_ech

Identify the sample size needed to detect a difference between two samples

ind.median - Indexes around median.

int.pop

Confidence interval of a population

int.prop

Confidence interval of a proportion

int.prop.table

Confidence intervals on a matrix of a contingent

jb.norm.test et jb.normtest

Jarque-Bera test for normality

kurtosis.norm.test

Kurtosis test for normality

biplt

make a biplot that allows you to see the relationship between two components of a PCA, the weight of the respective variables and to color by category pca, =c(1,2), ="blue", =0.25,xlab="cps",ylab="cps",cex=2,pch

corrigraph

igraph of correlated variables global or in relation to y

bootreg

Validating a bootstrap linear regression model

dsc

Obtain the best configuration to meet the objectives determined by one or more linear models.

dsc2

Check the robustness of a suggested dsc() prediction of X for objectives in Y by bootstrapping

dvar

Diversifies the variables of a dataframe by testing interactions, polynomials, logs... so that evolreg can draw a larger number of model combinations.

evolreg

Identify the best linear, logistic or mixed regression model using an evolutionary approach.

star - A function that transforms pvalues in stars ***

star.lm - Get stars for a linear model

valreg - Une fonction pour contrôler vos modèles linéaires simples, multiples ou mixtes et ne pas crier qu'une relation existe entre des variables numériques trop rapidement ! Idéale pour la validation de modèles linéaires et la validation de modèles linéaires mixtes.

exp_dyn

Dynamic expansion on a vector (changing the mean without necessarily changing the range of values)

lms.to.table

Make a table to summary coefficients of a list of linear models

meanbp

Moving average (weighted) per iteration

mm.test

Automatic mean/median comparison

Mode

Calculation of the mode of a dataset

pairwise

Automation function for pairwise calculations.

pairwise.boot

Calculate an pairwise difference between samples by bootstrap without encountering a central-limit problem

parco

Parallel coordinates in a single line of code

pareto

Pareto chart

pde

Vary two parameters in a recipe and model the ideal recipe.

rr

Gage R&R

skewness.norm.test

Skewness test for normality

wilcoxon.cut.test
