Respected sir

Good After Noon

Sir if we have metric DV and and two or more independent variables and among all independent variable one is categorical and all others are metric . And we want to control for the effect of some variables which are metric than which tool should I apply.

My dependent variables is RoE

Independent variables : promoters ownership ,  board size ,  proportion of independent directors these are metric independent variable . 

Position of chairman is a categorical independent variable .

Firm size , debt equity ratio , firm age , growth of sales are control variables of my study .

One addition here in 2 way ANOVA example:

If we wish to check the effect of gender on Sales then we'll use 2 indep sample t-test

If we wish to check the effect of exp on Sales then we'll use 1 way ANOVA

However if we wish to check the combined effect of Gender & Exp on Sales then we will use 2 way ANOVA

Here Null hypothesis will be that there are no significant differences among the sales of 6 groups:

Men with low exp

Women with low exp

Men with medium exp

Women with medium exp

Men with long exp

Women with long exp

Plz see we're looking at combined effect of Gender & Exp on Sales here, hence we'll use 2 way ANOVA

For the question of How to work on 2 way ANOVA, plz search for the post "Beyond ANOVA" on group

Best wishes

Dear Suman

Seema is correct in her advice. You shd use Multiple Regression.

I wish to clear there the concept of ANOCA (Analysis of Co-variance).

See when we've metric DV and one or more metric IDV then we shd use Regression (Simple or Multiple)

Ex: We wish to check whether Sales depends on Advt and No. of salesmen

Here Sales is metric DV

Advt is mtric IDV No of salesmen is metric IDV

So we'll use Multiple Regression here

----------------------------------------

However if there is one metric DV and one or more categorical IDVs then we use n-way ANOVA (n= No. of categorical IDV )

Ex: We wish to check whether Sales is related with Experience

Here Sales is metric DV

Experience is categorical IDV which >2 categories (Low exp, medium exp and Long exp)

so we shd 1- way ANOVA as there is 1 IDV

If we wish to check whether Sales is related with Experience and Gender

Here Sales is metric DV

Experience is categorical IDV

Gender is categorical IDV

So we shd use 2-way ANOVA here as there are 2 non-metric (categorical) IDV

----------------------------------------

Now if there are one metric IDV and rest all IDVs are categorical then we use a version of ANOVA which is called as n-way ANCOVA (n=No of categorical IDVs)

This metric IDV is called as Co-variate and is treated like a Control variable.

Ex: Whether Sales is related with Experience and Advt

Here Sales is metric DV

Experience is categorical IDV which >2 categories (Low exp, medium exp and Long exp)

Advt is metric IDV

Now there are 2 ways to analyze it:

If emphasis is on Advt and we wish to see this relation for the avrious exp categories then we shd use Regression with dummy vars

However if the emphasis is on the Exp and we wish to take Advt as control avr then we shd use 1-way ANOVA

where Advt is be called as Co-variate

Plz feel free to ask for ur doubts now.

Your dep and independent variables are metric in nature. So go for multiple regression.

First of all please tell about your data. If data is panel and only one dependent variable is there with many independent variables , multiple regression will be suitable.

Respected sir

Good evening

Sir I am working on a research paper and my variables of interest are as follows

Dependent variable = RoE

Independent variables = promoter's ownership , FII ownership,  banking and financial services institution ownership, public ownership , mutual fund ownership

Along with these variables there are certain control variables also such as growth rate of sales

Age of firm

Debt: equity ratio

Size of firm measured in total assets of companies 

Sir I want to know which test I have to apply  mutilate regression or ANCOVA and how it is applied.

Dear Suman madam can u tell me what is the sources of ur data 

[Neeraj Kaushik]

Dear Suman

If you get only 1 categorical IDV then u can use Dummy for that.

Moreover if u wish to take some var(s) as control then u shd use Hierarchical Regression (can be done in SPSS).

Here we take all var(s) in model 1-by-1. So its different from ENTER or Stepwise method.

[Seema Malik]

You can apply multiple regression with dummy variable(categorical independent variable).
