How do you find Y-intercept and slope values on simple regression model with SPSS program?

where "Y est" equals the estimated value on dependent variable, "a" equals the intercept (supplied by SPSS),  "b" equals the slope (supplied by SPSS), and "X" equals the given value on the independent variable.

standard deviation of intercept is a quantity related to the precision of the estimated intercept of the fitted line. It can be calculated by the formula:\n\nS_a = (S_b)*(sqrt( (sum(x_j)^2)/m )) \n\nWhere, S_b is standard deviation of slope\n\nS_b = sqrt( ((m*(s_y)^^2) / [m*(sum(x_j)^2) -(sum x_j)^2] )\n\ns_y is the residual standard deviation.\n\na and b are estimated parameters of the line y = a + bx +err.\n\n[Here, by S_b, I mean S with suffix b, Sorry but its a bit difficult to type mathematics with only text.]\nI hope , I answered your question.

use the slope formula.\n\ny sub 2 minus y sub 1 divided by x sub 2 minus y sub 1\n\nthen you get 1-5 divided by 0-2\n\nthen you get -4 divided by -2\n\nthe answer is 2

If you are given the slope(m) and a point on the line(x1, y1) you can write the equation of the line.\n\nYou take the y-intercept equation\ny =m*x + b and substitute x1 and y1 for x and y and get\ny1 = m*x1 + b    \nnow solve for b\nb = (y1-m*x1)\nsubstite b = (y1-m*x1) into the y-intercept equation\ny =m*x +(y1-m*x1)\nsubtract y1 from both sides of the equation\ny -y1 = m*x -m*x1\nbecomes the point-slope formula\ny -y1 =m*(x-x1)

there are a couple of ways to do this, but I think the easiest is to find the slope and since you know the y-intercept, use that formula.\n\nm= (-4-0)/(0-12)\n\nm=-4/-12\nm=1/3\n\ny=(1/3)x -4

The statement is true.  The formula for the slope of the regression line is\n\nr(SDy)/SDx\n\nSince SDy and SDx are always positive, then the only thing that determines the sign of the slope is r, the correlation coefficient.  So if r is positive, then the slope is positive; if r is negative, then the slope is negative.

This is for math right? If so:\n\nThe slope-intercept form is:\n\ny = mx + b\n\ny = value on the y-axis\nm = slope\nx = value on the x-axis\nb = y-axis intercept\n\nThe slope-intercept form gives the equation for a straight line.

y = mx + b is the slope intercept form, where m = slope\n\nso 2 is the slope in your example\n\nWith any equation for a line, there are 2 variables, x and y, representing the position on the x and y axis.  Given any line equation, you can manipulate it to get it into slope intercept form (y = mx + b), and m will be your slope.\n\nThe y-intercept is where the line crosses the y-axis (or where x = 0).  As you can see, if you put x = 0 in the equation, you will get:\n\ny = 0x + b\ny = b\n\nso when x = 0, y = b.\n\nHope this helps! :)

Using a simple TI-83, the data in #3 gives a linear regression equation of\ny = 0.4668x - 31.737, where y is absences and x is temperature.  r = 0.977.\n\nSound like you've been partying too much and ignoring your classes.  Well, you get what you choose.

just use SPSS 13.0  ;)

The standard equation for slope-intercept form is y=mx+b. m is the slope and b is the y-coordinate of the vertical (y) intercept\n\n-2x=y+3       Original equation\n\ny=-2x-3        Rewritten in S-I form\n\nm= -2, b= -3\n\nThis means that the graph of the funtion is a line through the y-axis at the point (0, -3) with a slope of (-2)

slope equals rise/run. slope=4 y-intercept=-20

No, you must use algebra to plot lines. How else would you explain the variables x and y?\n\nSlope-intercept form looks like this:\n\ny = mx+b\n\nOr, in the case of vertical lines:\n\nx = my+b\n\nWhere m is the slope and b is the x- or y- intercept, depending on which one you are using.

The slope-intercept form for a line is y=mx+b, wherem is the slope and b is the y-intercept. Comparing this form to y=7x+3, you see that m=7 (the slope) and b=3 (the y-intercept).

Check out this website it might help a bit possibly!?  I use SPSS 14.0 so I'm not sure about the differences but this site is for 13.0 ...http://www.ats.ucla.edu/STAT/SPSS/output/reg_spss.htm\n\nHowever, I'm not sure how familiar you are but the stepwise multiple regression is selected in SPSS by using the Method text box on the Linear Regression box.  You need no particular order but the variables are entered into the analysis such that those that produce the largest increase in the multiple R are entered first.  For instance, if you did not have a particular theory but you wanted to see which of the variables best predicted the outcome variable, SPSS will do this for you based on the extent to which they increased the mutiple R. \n\nHope this helps! Good luck!!
