Application of methods that deal with reasonably large numbers of measurements made on each object in one or more samples simultaneously”.Many statistical techniques focus on just one or two variables. Multivariate analysis techniques help to analyse more than two variables at once. The final goal of these analyses is both information or prediction, i.e., more than just discovering an association.
Analysis of dependence:- Where one or more variables are dependent variables, to be explained or predicted by others. e.g. Discriminant analysis, Multiple regression, Manova, Partial Least Square.
Analysis of interdependence:- No variables thought of as “dependent”. Resemble at the associations among independent and dependent variables, objects or cases. Example: a principal component analysis.cluster analysis, factor analysis.
The prediction equation is: Y' = A+BX, where Y' = the predicted dependent variable, A = Constant, B = unstandardized regression coefficient, and X = value of the predictor variable. To predict the students’ GPA scores from their reading scores use the values presented in the Unstandardized Coefficients column. Using the Constant and B values, the prediction equation would be: Predicted GPA = –0.111 + (0.061 × READ) Thus, the student who has a reading score of 56, the predicted GPA score will be: Predicted GPA = –0.111 + (0.061 × 56)= 3.31 However, in the Model Summary table, the Standard Error of the Estimate is 0.32848. This means that at the 95% confidence interval, the predicted GPA the score of 3.31 lies between the scores of 2.66 (3.31 – (1.96 × 0.32848)) and 3.95 (3.31 + (1.96 × 0.32848)).
PhDstatistics uses effective methods to reach at the solution using various multivariate analysis techniques by leveraging full use to tools and statistics used by the best statisticians
Methods for classifying separate groups of related cases. Also applied to compile data by representing segments of similar cases in the data. This technique of cluster analysis is known as “dissection.
Is a statistical method for analysing individuals or objects into exhaustive groups and mutually exclusive on the basis of a set of independent variables.
“Statistical approach used to explain the variability between examined variables in words of a probably lower number of unobserved variables which are called factors”. Factor analysis attempts toRead More

Statis is applied when at least one dimension of the three-way table is common to all tables. The first step of the method performs a PCA of each table and generates a similarity table between the units for each table.
PhDstatistics has come up with an effective agenda to reach beneficiaries such as integrity of data, confidentiality and quality of analysis by leveraging the following steps:
Although data management could seem harrowing to undertake, one need not apply a big bang approach to it. Instead we at PhDstatistics try to prioritize on target areas in need of improved results as per the study
Thanks to our experts with diverse information and access to different variables softwares to make your statistical analysis at the best possible manner by integrating all the resources together.
A researcher will have greater insights into the data, but it could be tedious for one to understand the integrity of the same in terms of situations where quality issues could continue or worsen. We aid in providing all sorts of integrations.
