This chapter covers descriptive/summary statistics in tidy R, including descriptive statistics of a single variable (central tendency and dispersion), a single variable within groups, and pairs of variables.Sumner, Jane L.University of Minnesota...
(default 95%).## data: a data frame.## measurevar: the name of a column that contains the variable to be summariezed## groupvars: a vector containing names of columns that contain grouping variables## na.rm: a boolean that indicates whether to ignore NA's## conf.interval: the ...
This can be done via Homebrew and setting environment variables to point to relevant library and header files: $ brew install openblas $ export SYSTEM_VERSION_COMPAT=1 $ export LAPACK=/usr/local/opt/openblas/lib $ export LAPACK_SRC=/usr/local/opt/openblas/include $ export BLAS=/usr/local/op...
The Markov chain model discretizes the pedestrian motion state into a finite number of state variables, and studies the switching relationship between different state variables. Kwak et al. established a corresponding probability density function to estimate the state switching probability by using the ...
We conducted two power analyses using G*Power 3 to identify the appropriate sample size for the main analyses. The first analysis tested a MANOVA with special effects and interactions for two groups (summary and reread), three predictors (knowledge scores, and five response variables (essay scores...

And if I want to do three dimensions, I put all three variables in my table() function. R will give me the 2×2 table of sex and marital status, stratified by the third variable, migrant status. table3<-table(mydata$Sex, mydata$Married, mydata$Migrantstatus) The great part about ...
aThese experimenters used the t test as a method of summarizing their independent variables, but they used no normative model in the sense that the term has been used here. That is, they did not use a statistical model to prescribe the optimal confidence statement. 这些实验者使用了t测试作为...
We cycle through block variables in a deterministic or- der (AX, AY, BX, then BY). For AX, we solve a quadratic program (QP) on each column vector αXi using the Fast It- erative Shrinkage-Thresholding Algorithm (FISTA) [2]: min α∈∆p xi − Zα 2 2 (3) We use the ...
Then, from the entry point in the control flow graph,we propagate variables'taint tags by applying forward data-flow analysis. We denote by taint(v) the tag for a variable v. The taint tag can be used to identify the types of evidence. At meanwhile, we track where the evidence is ...
