comparable. Not to mention stata .. Sas has gradually become incomparable. Python and r have their own advantages. To put it simply, these two tools are very popular in cs and statistics. In contrast, python can better reflect the thinking of cs, and r is basically an application carried from theory to implementation for statistics. Of course, this has a profound relationship with the history of these two languages. Python is closely related to c, an

of the Intel 82545EM Gigabit Ethernet card, and basically all of the OS are E1000 driven, so compatibility is the best. Vmxnet 2 is an older generation of parallel virtual web, only applicable to esx/esxi3.5 and above the limited customer operating system, vmxnet 3 relatively new, but it seems only applicable to virtual machine version 7 virtual machine (virtual machine version set in the first two steps, The version recommended for use in ESXI5 is 8). These two cards provide better performance

In VMware vsphere Web client, you can add a new SCSI controller to the VM. The options include the following types. What are their differences? How to choose? Buslogic parallel One of the earliest vscsi controllers on the VMware platform. the first version of Windows has its driver by default, making it easier to install a specific version of Windows. the performance is incomparable with that of the LSI logic driver. Because the queue depth in the Windows Driver is limited to 1, the LSI lo

/blog_65efeb0c0100htz7.html Common normal test methods for SPSS and SAS Many analytical methods of measurement data require that the data distribution is normal or approximate normal, so it is necessary to test the original independent data for normality.By plotting the frequency distribution histogram of the data, the normality of data distribution is qualitatively judged. Such a graphical judgment is by no means a rigorous test of normality, and the
