Matrices are everywhere. If you have used a spreadsheet program such as MS-Excel, Lotus or written a table (such as in Ms-Word) or even have used mathematical or statistical software such a Mathematica, Matlab, Minitab, SAS, SPSS and Eviews etc., you have used a matrix. Matrices make the presentation of numbers clearer and make calculations […]

In early civilizations, the number of animals (sheep, goat, and camel etc.) or children people have were tracked by using different methods such as people match the number of animals with the number of stones. Similarly, they count the number of children with the number of notches tied on a string or marks on a […]

The Z-Score The Z-score also referred to as standardized raw scores is a useful statistic because not only permits to compute the probability (chances or likelihood) of raw score (occurring within normal distribution) but also it helps to compare two raw scores from different normal distributions. The Z-score is a dimensionless measure since it is […]

Multicollinearity in Linear Regression Models The objective of multiple regression analysis is to approximate the relationship of individual parameters of a dependency, but not of interdependency. It is assumed that the dependent variable and regressors ‘s are linearly related to each other (Graybill, 1980; Johnston, 1963 and Malinvaud, 1968). Therefore, inferences depicted from any regression […]

Levels of Measurement (Scale of Measure) Level of measurement (scale of measure) have been classified into four categories. It is important to understand these level of measurement, since these level of measurement play important part in determining the arithmetic and different possible statistical tests that are carried on the data. The scale of measure is […]

In R Language, a vector is the simplest data structure. A vector in R is also an object that contains elements having the same data type. To create a vector (say ‘x’) of the same type (say double) of elements consisting of five elements one can use c() function. For example, Creating a vector in […]

Reading and Writing Data in R Reading Data in R For reading (importing) data into R following are some functions. read.table(), and read.csv(), for reading tabular data readLines() for reading lines of a text file source() for reading in R code files (inverse of dump) dget() for reading in R code files (inverse of dput) […]

In R language, list is an object that consists of an ordered collection of objects known as its components. A list in R Language is a structured data that can have any number of any modes (types) of other structured data. That is, one can put any kind of object (like vector, data frame, character […]

The R program’s structure is similar to the programs written in other computer languages such as C or its successors C++ and Java. However, important differences between these languages and R are (i) R has no header files, (ii) most of the declarations are implicit, (iii) there are no pointers in R, and (iv) text […]

The problem of multicollinearity plagues the numerical stability of regression estimates. It also causes some serious problem in validation and interpretation of the regression model.Â Consider the usual multiple linear regression model, , where is an vector of observation on dependent variable, is known design matrix of order , having full-column rank , is vector of […]

R language provides an interlocking suite of facilities that make fitting statistical models very simple. The output from statistical models in R language is minimal and one needs to ask for the details by calling extractor functions. Defining Statistical Models; Formulae in R Language The template for a statistical model is a linear regression model […]

i appreciate you sir!

Hi Muhammad Imdadullah,

Thanks for posting a comment on my blog. I have included your blog in my blog feed. Keep up the good posts!

AsSalam O Alakam, This is MYaseen208. Please drop me an email. Thanks

A.o.a … imdad sb u did really nice work ,, uploading the statistical software … but i want to say that there is missing basic software like minitab ,,, spss … and Eview

I can’t gave download links of registered or priced softwares. I am sharing initially 100% softwares, most of them fulfills our many statistical needs and even solve many statistical problems. For minitab, SPSS, Eview I am trying to write their tutorial rather than sharing there pirated versions.

sir plz add interviw questions which mostly asked in interviwe

Its good idea, but initially its better if students appearing in different interviews provide some information about questions asked. Actually I am doing all the things myself. Its very difficult to maintain, run and update a website with unique contents.

A.A..

Hope you will be fine. I discoverd your site while I was just looking for SPSS model papers and some helping metrial regarding to mcqs on SPSS. It was a nice experience to see your hard work. It is quite appreciating. Please inform me if I would assist you in this regard.

Regards!

Sir, you are doing great job….really it is very helpful…..i want to say, thank you so much…kindly check the question # 3 in test 4 related the topic “regression and correlation”….i think the correct answer is option A….the line is parallel to x-axis….but the computer shows option D as right answer…. kindly check it out đŸ™‚

regards

W.A.

Thanks for liking the work.

Checked the question and found correct.

The question is related to equation such as y=k, which means that as x increases or decreases, y remains the constant hence line is parallel to the x-axis. One can also say that A line having a Zero Slope is Horizontal.

Thanks again for visiting and commenting

You can download all available MCQS from sites.

Asslam o Alaikum,

sir would this material be enough for Public service Commission paper ( One paper commission) for Statistical Officer??

Good job…stay blessed

Salam Sir,

I Rahmat hassan from Gilgit student of statistics, Sir i would like to take some tips about FPSC b/c i visit your web page and gain much of information about my subjects.

Kindly help me sir

Thankyou Sir

AOA

Imdad Bhai , Good Job sir
