High-level languages are translated into machine language using a compiler or an interpreter or a combination of the two. They are easier and more efficient for programmers because they are closer to natural languages than machine languages.
#XLSTAT ERROR SOFTWARE#
The majority of software is written in high-level programming languages. As of 2015, most personal computers, smartphone devices and servers have processors with multiple execution units or multiple processors performing computation together, and computing has become a much more concurrent activity than in the past. The processor executes the instructions in the order they are provided, unless it is instructed to "jump" to a different instruction, or is interrupted by the operating system. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen causing state changes which should be visible to the user. For example, an instruction may change the value stored in a particular storage location in the computer-an effect that is not directly observable to the user. Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state.
#XLSTAT ERROR CODE#
This is in contrast to hardware, from which the system is built and which actually performs the work.Īt the lowest programming level, executable code consists of machine language instructions supported by an individual processor-typically a central processing unit (CPU) or a graphics processing unit (GPU). Software is a set of computer programs and associated documentation and data. The application software layer interfaces with the operating system, which in turn communicates with the hardware. For beta coefficients, XLStat remove the intercept.A diagram showing how the user interacts with application software on a typical desktop computer. Ps contrasts in R and Xlstat are sum(ai)=0. According to my thoughts and publications I read, it doesn't have any sense … Then, I would like to ask you about the relevance of these beta coefficients for a categorical variable. So, my question is this one : what is the formula to obtain the beta coefficient in a one way Anova ? Moreover, I conducted the anova on Statistica in order to see if XLStat did any mistake but its outputs for the beta coefficients are the same than in Xlstat … Given that the first one is the same with R and XLStat, I suppose that Xlstat convert too the categorical variable in numeric variable (which is senseless but this is not the question). The first beta I obtained with R is the same than in XLstat, but not the second and the third. sd(x) being the standard deviation of the categorical variable (which is automatically transformed as numeric variable with R, in order to calculate sd(x), seems logical ) and sd(y) being the standard deviation of my response variable.
Firstly, I was surprised, because I didn’t think we could calculate beta coefficient for a categorical variable and according to the bibliography I read, it doesn’t have any sense.Īnyway, I tried to find these coefficients with R, thanks to the unique formula I found : beta = estimate * sd(x)/sd(y). However, XLstat offers an extra output : the standardized coefficients (called too beta coefficients). I’ve conducted this ANOVA on R and XLStat and the outputs for the F fisher, p-value, coefficient estimations, t-values, std error … are exactly the same. I’ve conducted an one-way ANOVA (my categorical variable is 3 modal (1,2,3) and my response variable is quantitative on scale 1-10). I’m working with the software R and XLStat.
